f4050ccab7 Docs/damon/maintainer-profile: update deprecated awslabs GitHub URLs
DAMON GitHub repos have moved from awslabs GitHub org to damonitor org[1].
Following the change, URLs on documents are also updated[2].  However,
commit 2e9b3d6e2e ("Docs/damon/maintainer-profile: add links in place"),
which was added just after the update, was using the deprecated GitHub
URLs.  Update those to use damonitor GitHub URLs instead.

Patch series "Docs/damon/maintainer-profile: a couple of minor hotfixes".

DAMON maintainer-profile.rst file patches[1] that were merged into the
v6.12-rc1 have a couple of minor mistakes.  Fix those.

[1] https://lore.kernel.org/20240826015741.80707-1-sj@kernel.org


This patch (of 2):

Links to external web pages on DAMON's maintainer-profile.rst are missing
'_' suffixes.  As a result, rendered document is having only verbose URLs
that cannot be clicked.  Fix those.

Also, update the link texts for git trees to contain the names of the
trees, for better readability and avoiding below Sphinx warning.

    maintainer-profile.rst:4: WARNING: Duplicate explicit target name: "tree".

1f455f601e timers/Documentation: Cleanup delay/sleep documentation
The documentation which tries to give advices how to properly inserting
delays or sleeps is outdated. The file name is 'timers-howto.rst' which
might be misleading as it is only about delay and sleep mechanisms and not
how to use timers.

Update the documentation by integrating the important parts from the
related function descriptions and move it all into a self explaining file
with the name "delay_sleep_functions.rst".

Also add macros for the NMI and IRQ0-15 interrupts which map the
SPI0-16 interrupts on the RZ/V2H(P) SoC so that they can be
used in the first cell of the interrupt specifiers.

For the second cell of the interrupt specifier, since NMI, IRQn

add helper macros to make it easier for the user to work out what's
available.

caf0ea451d iomap: remove iomap_file_buffered_write_punch_delalloc
Currently iomap_file_buffered_write_punch_delalloc can be called from
XFS either with the invalidate lock held or not.  To fix this while
keeping the locking in the file system and not the iomap library
code we'll need to life the locking up into the file system.

To prepare for that, open code iomap_file_buffered_write_punch_delalloc
in the only caller, and instead export iomap_write_delalloc_release.

f7e1d19105 Documentation/tracing: Mention that RESET_ATTACK_MITIGATION can clear memory
At the 2024 Linux Plumbers Conference, I was talking with Hans de Goede
about the persistent buffer to display traces from previous boots. He
mentioned that UEFI can clear memory. In my own tests I have not seen
this. He later informed me that it requires the config option:

 CONFIG_RESET_ATTACK_MITIGATION

It appears that setting this will allow the memory to be cleared on boot
up, which will definitely clear out the trace of the previous boot.

Add this information under the trace_instance in kernel-parameters.txt
to let people know that this can cause issues.

Merge patch series "ovl: file descriptors based layer setup"
Christian Brauner <brauner@kernel.org> says:

Currently overlayfs only allows specifying layers through path names.
This is inconvenient for users such as systemd that want to assemble an
overlayfs mount purely based on file descriptors.

When porting overlayfs to the new mount api I already mentioned this.
This enables user to specify both:

     fsconfig(fd_overlay, FSCONFIG_SET_FD, "upperdir+", NULL, fd_upper);
     fsconfig(fd_overlay, FSCONFIG_SET_FD, "workdir+",  NULL, fd_work);
     fsconfig(fd_overlay, FSCONFIG_SET_FD, "lowerdir+", NULL, fd_lower1);
     fsconfig(fd_overlay, FSCONFIG_SET_FD, "lowerdir+", NULL, fd_lower2);

in addition to:

     fsconfig(fd_overlay, FSCONFIG_SET_STRING, "upperdir+", "/upper",  0);
     fsconfig(fd_overlay, FSCONFIG_SET_STRING, "workdir+",  "/work",   0);
     fsconfig(fd_overlay, FSCONFIG_SET_STRING, "lowerdir+", "/lower1", 0);
     fsconfig(fd_overlay, FSCONFIG_SET_STRING, "lowerdir+", "/lower2", 0);

The selftest contain an example for this.

aeb218d900 docs: netdev: document guidance on cleanup patches
The purpose of this section is to document what is the current practice
regarding clean-up patches which address checkpatch warnings and similar
problems. I feel there is a value in having this documented so others
can easily refer to it.

Clearly this topic is subjective. And to some extent the current
practice discourages a wider range of patches than is described here.
But I feel it is best to start somewhere, with the most well established
part of the current practice.

Merge patch series "timekeeping/fs: multigrain timestamp redux"
Jeff Layton <jlayton@kernel.org> says:

The VFS has always used coarse-grained timestamps when updating the
ctime and mtime after a change. This has the benefit of allowing
filesystems to optimize away a lot metadata updates, down to around 1
per jiffy, even when a file is under heavy writes.

Unfortunately, this has always been an issue when we're exporting via
NFSv3, which relies on timestamps to validate caches. A lot of changes
can happen in a jiffy, so timestamps aren't sufficient to help the
client decide when to invalidate the cache. Even with NFSv4, a lot of
exported filesystems don't properly support a change attribute and are
subject to the same problems with timestamp granularity. Other
applications have similar issues with timestamps (e.g backup
applications).

If we were to always use fine-grained timestamps, that would improve the
situation, but that becomes rather expensive, as the underlying
filesystem would have to log a lot more metadata updates.

What we need is a way to only use fine-grained timestamps when they are
being actively queried. Use the (unused) top bit in inode->i_ctime_nsec
as a flag that indicates whether the current timestamps have been
queried via stat() or the like. When it's set, we allow the kernel to
use a fine-grained timestamp iff it's necessary to make the ctime show
a different value.

This solves the problem of being able to distinguish the timestamp
between updates, but introduces a new problem: it's now possible for a
file being changed to get a fine-grained timestamp. A file that is
altered just a bit later can then get a coarse-grained one that appears
older than the earlier fine-grained time. This violates timestamp
ordering guarantees.

To remedy this, keep a global monotonic atomic64_t value that acts as a
timestamp floor.  When we go to stamp a file, we first get the latter of
the current floor value and the current coarse-grained time. If the
inode ctime hasn't been queried then we just attempt to stamp it with
that value.

If it has been queried, then first see whether the current coarse time
is later than the existing ctime. If it is, then we accept that value.
If it isn't, then we get a fine-grained time and try to swap that into
the global floor. Whether that succeeds or fails, we take the resulting
floor time, convert it to realtime and try to swap that into the ctime.

We take the result of the ctime swap whether it succeeds or fails, since
either is just as valid.

Filesystems can opt into this by setting the FS_MGTIME fstype flag.
Others should be unaffected (other than being subject to the same floor
value as multigrain filesystems).

spi: intel: Add protected and locked attributes
The manufacturing access to the PCH/SoC SPI device is traditionally
performed via userspace driver accessing registers via /dev/mem but due
to security concerns /dev/mem access is being much restricted, hence the
reason for utilizing dedicated Intel PCH/SoC SPI controller driver,
which is already implemented in the Linux kernel.

Intel PCH/SoC SPI controller protects the flash storage via two
mechanisms one is the via region protection registers and second via
BIOS lock. The BIOS locks only the BIOS regions usually 0 and/or 6.

The device always boots with BIOS lock set, but during manufacturing the
BIOS lock has to be lifted in order to enable the write access. This can
be done by passing "writeable=1" in the command line when the driver is
loaded. This "locked" state is exposed through new sysfs attributes
(intel_spi_locked, intel_spi_bios_locked).

Second, also the region protection status is exposed via sysfs attribute
(intel_spi_protected) as the manufacturing will need the both files in
order to validate that the device is properly sealed.

Includes code written by Tamar Mashiah.

6df1197815 dt-bindings: interrupt-controller: fsl,ls-extirq: workaround wrong interrupt-map number
The driver(drivers/irqchip/irq-ls-extirq.c) have not use standard DT
function to parser interrupt-map. So it doesn't consider '#address-size'
in parent interrupt controller, such as GIC.

When dt-binding verify interrupt-map, item data matrix is spitted at
incorrect position. So cause below warning:

arch/arm64/boot/dts/freescale/fsl-ls1088a-qds.dtb: interrupt-controller@14:

is too short

Remove interrupt-map restriction to workaround this warning for
'fsl,ls1088a-extirq', 'fsl,ls2080a-extirq' and fsl,lx2160a-extirq.
Other keep the same restriction.

a2471684da crypto: ecdsa - Move X9.62 signature size calculation into template
software_key_query() returns the maximum signature and digest size for a
given key to user space.  When it only supported RSA keys, calculating
those sizes was trivial as they were always equivalent to the key size.

However when ECDSA was added, the function grew somewhat complicated
calculations which take the ASN.1 encoding and curve into account.
This doesn't scale well and adjusting the calculations is easily
forgotten when adding support for new encodings or curves.  In fact,
when NIST P521 support was recently added, the function was initially
not amended:

https://lore.kernel.org/all/b749d5ee-c3b8-4cbd-b252-7773e4536e07@linux.ibm.com/

Introduce a ->max_size() callback to struct sig_alg and take advantage
of it to move the signature size calculations to ecdsa-x962.c.

Introduce a ->digest_size() callback to struct sig_alg and move the
maximum ECDSA digest size to ecdsa.c.  It is common across ecdsa-x962.c
and the upcoming ecdsa-p1363.c and thus inherited by both of them.

For all other algorithms, continue using the key size as maximum
signature and digest size.

221f00418e crypto: sig - Rename crypto_sig_maxsize() to crypto_sig_keysize()
crypto_sig_maxsize() is a bit of a misnomer as it doesn't return the
maximum signature size, but rather the key size.

Rename it as well as all implementations of the ->max_size callback.
A subsequent commit introduces a crypto_sig_maxsize() function which
returns the actual maximum signature size.

While at it, change the return type of crypto_sig_keysize() from int to
unsigned int for consistency with crypto_akcipher_maxsize().  None of
the callers checks for a negative return value and an error condition
can always be indicated by returning zero.

6b34562f0c crypto: akcipher - Drop sign/verify operations
A sig_alg backend has just been introduced and all asymmetric
sign/verify algorithms have been migrated to it.

The sign/verify operations can thus be dropped from akcipher_alg.
It is now purely for asymmetric encrypt/decrypt.

Move struct crypto_akcipher_sync_data from internal.h to akcipher.c and
unexport crypto_akcipher_sync_{prep,post}():  They're no longer used by
sig.c but only locally in akcipher.c.

In crypto_akcipher_sync_{prep,post}(), drop various NULL pointer checks
for data->dst as they were only necessary for the verify operation.

In the crypto_sig_*() API calls, remove the forks that were necessary
while algorithms were converted from crypto_akcipher to crypto_sig
one by one.

In struct akcipher_testvec, remove the "params", "param_len" and "algo"
elements as they were only needed for the ecrdsa verify operation.
Remove corresponding dead code from test_akcipher_one() as well.

crypto_akcipher to a new crypto_sig frontend.

Internally, the crypto_sig frontend still uses akcipher_alg as backend,
however:

   "The link between sig and akcipher is meant to be temporary.  The
    plan is to create a new low-level API for sig and then migrate
    the signature code over to that from akcipher."
    https://lore.kernel.org/r/ZrG6w9wsb-iiLZIF@gondor.apana.org.au/

   "having a separate alg for sig is definitely where we want to
    be since there is very little that the two types actually share."
    https://lore.kernel.org/r/ZrHlpz4qnre0zWJO@gondor.apana.org.au/

Take the next step of that migration and augment the crypto_sig frontend
with a sig_alg backend to which all algorithms can be moved.

During the migration, there will briefly be signature algorithms that
are still based on crypto_akcipher, whilst others are already based on
crypto_sig.  Allow for that by building a fork into crypto_sig_*() API
calls (i.e. crypto_sig_maxsize() and friends) such that one of the two
backends is selected based on the transform's cra_type.

ac30860956 arm64 fixes for 6.12-rc2:
- Expand the speculative SSBS workaround to cover Cortex-A715,

 - Force position-independent veneers - in some kernel configurations,
   the LLD linker generates position-dependent veneers for otherwise
   position-independent code, resulting in early boot-time failures
 
 - Fix Kconfig selection of HAVE_DYNAMIC_FTRACE_WITH_ARGS so that it is

2f91ff27b0 sound fixes for 6.12-rc2
Slightly high amount of changes in this round, partly because of my
 vacation in the last weeks.  But all changes are small and nothing
 looks worrisome.
 
 The biggest LOCs is MAINTAINERS updates, and there is a core change
 for card-ID string creation for non-ASCII inputs.  Others are rather
 device-specific, such as new quirks and device IDs for ASoC, usual
 HD-audio and USB-audio quirks and fixes, as well as regression fixes
 in HD-audio HDMI audio and Conexant codec.

830ae8a396 arm64: Document boot requirements for Guarded Control Stacks
FEAT_GCS introduces a number of new system registers, we require that
access to these registers is not trapped when we identify that the feature
is present.  There is also a HCRX_EL2 control to make GCS operations
functional.

Since if GCS is enabled any function call instruction will cause a fault
we also require that the feature be specifically disabled, existing
kernels implicitly have this requirement and especially given that the
MMU must be disabled it is difficult to see a situation where leaving
GCS enabled would be reasonable.

c6929644c1 dt-bindings: net: xlnx,axi-ethernet: Add missing reg minItems
Add missing reg minItems as based on current binding document
only ethernet MAC IO space is a supported configuration.

There is a bug in schema, current examples contain 64-bit
addressing as well as 32-bit addressing. The schema validation
does pass incidentally considering one 64-bit reg address as
two 32-bit reg address entries. If we change axi_ethernet_eth1
example node reg addressing to 32-bit schema validation reports:

Documentation/devicetree/bindings/net/xlnx,axi-ethernet.example.dtb:
ethernet@40000000: reg: [[1073741824, 262144]] is too short

To fix it add missing reg minItems constraints and to make things clearer
stick to 32-bit addressing in examples.

qrb4210-rb2: add HDMI audio playback support
Merge series from Alexey Klimov <alexey.klimov@linaro.org>:

This series still keeps "qcom,qrb4210-rb2-sndcard" for sm8250 soundcard. As per
off the list discussion with Srini it was suggested to have it since in future it
may be required to add clocks, workarounds, quirks, model-specific things based on
this compatible. The same as for RB5 compatible in sm8250 snd driver.

This focuses on HDMI audio playback only hence there are no soundwire and dmic pins,
for instance. The work to enable playback via wcd+wsa8815 amplifier is in progress (it works)
and one of the routes is to merge such two patchsets together.

ASoC: dt-bindings: davinci-mcasp: Fix interrupts property
My understanding of the interrupts property is that it can either be:
1/ - TX
2/ - TX
   - RX
3/ - Common/combined.

There are very little chances that either:
   - TX
   - Common/combined
or even
   - TX
   - RX
   - Common/combined
could be a thing.

Looking at the interrupt-names definition (which uses oneOf instead of
anyOf), it makes indeed little sense to use anyOf in the interrupts
definition. I believe this is just a mistake, hence let's fix it.

Merge patch series "Fixup NLM and kNFSD file lock callbacks"
Benjamin Coddington <bcodding@redhat.com> says:

Last year both GFS2 and OCFS2 had some work done to make their locking more
robust when exported over NFS.  Unfortunately, part of that work caused both
NLM (for NFS v3 exports) and kNFSD (for NFSv4.1+ exports) to no longer send
lock notifications to clients.

This in itself is not a huge problem because most NFS clients will still
poll the server in order to acquire a conflicted lock, but now that I've
noticed it I can't help but try to fix it because there are big advantages
for setups that might depend on timely lock notifications, and we've
supported that as a feature for a long time.

Its important for NLM and kNFSD that they do not block their kernel threads
inside filesystem's file_lock implementations because that can produce
deadlocks.  We used to make sure of this by only trusting that
posix_lock_file() can correctly handle blocking lock calls asynchronously,
so the lock managers would only setup their file_lock requests for async
callbacks if the filesystem did not define its own lock() file operation.

However, when GFS2 and OCFS2 grew the capability to correctly
handle blocking lock requests asynchronously, they started signalling this
behavior with EXPORT_OP_ASYNC_LOCK, and the check for also trusting
posix_lock_file() was inadvertently dropped, so now most filesystems no
longer produce lock notifications when exported over NFS.

I tried to fix this by simply including the old check for lock(), but the
resulting include mess and layering violations was more than I could accept.
There's a much cleaner way presented here using an fop_flag, which while
potentially flag-greedy, greatly simplifies the problem and grooms the
way for future uses by both filesystems and lock managers alike.

d0a0c91dff dt-bindings: display: elgin,jg10309-01: Add own binding
Currently, the compatible 'elgin,jg10309-01' is documented inside
trivial-devices.yaml, but it does not fit well there as it requires
extra properties such as spi-max-frequency, spi-cpha, and spi-cpol.

This causes the following dt-schema warnings:

  DTC [C] arch/arm/boot/dts/rockchip/rv1108-elgin-r1.dtb

081eb7932c arm64: errata: Expand speculative SSBS workaround once more
A number of Arm Ltd CPUs suffer from errata whereby an MSR to the SSBS
special-purpose register does not affect subsequent speculative
instructions, permitting speculative store bypassing for a window of
time.

We worked around this for a number of CPUs in commits:

* 7187bb7d0b ("arm64: errata: Add workaround for Arm errata 3194386 and 3312417")
* 75b3c43eab ("arm64: errata: Expand speculative SSBS workaround")
* 145502cac7ea70b5 ("arm64: errata: Expand speculative SSBS workaround (again)")

Since then, a (hopefully final) batch of updates have been published,
with two more affected CPUs. For the affected CPUs the existing
mitigation is sufficient, as described in their respective Software
Developer Errata Notice (SDEN) documents:

* Cortex-A715 (MP148) SDEN v15.0, erratum 3456084
  https://developer.arm.com/documentation/SDEN-2148827/1500/

* Neoverse-N3 (MP195) SDEN v5.0, erratum 3456111
  https://developer.arm.com/documentation/SDEN-3050973/0500/

Enable the existing mitigation by adding the relevant MIDRs to
erratum_spec_ssbs_list, and update silicon-errata.rst and the
Kconfig text accordingly.

* KVM currently invalidates the entirety of the page tables, not just
   those for the memslot being touched, when a memslot is moved or deleted.
   The former does not have particularly noticeable overhead, but Intel's
   TDX will require the guest to re-accept private pages if they are
   dropped from the secure EPT, which is a non starter.  Actually,
   the only reason why this is not already being done is a bug which
   was never fully investigated and caused VM instability with assigned
   GeForce GPUs, so allow userspace to opt into the new behavior.
 
 * Advertise AVX10.1 to userspace (effectively prep work for the "real" AVX10
   functionality that is on the horizon).
 
 * Rework common MSR handling code to suppress errors on userspace accesses to
   unsupported-but-advertised MSRs.  This will allow removing (almost?) all of
   KVM's exemptions for userspace access to MSRs that shouldn't exist based on
   the vCPU model (the actual cleanup is non-trivial future work).
 
 * Rework KVM's handling of x2APIC ICR, again, because AMD (x2AVIC) splits the
   64-bit value into the legacy ICR and ICR2 storage, whereas Intel (APICv)
   stores the entire 64-bit value at the ICR offset.
 
 * Fix a bug where KVM would fail to exit to userspace if one was triggered by
   a fastpath exit handler.
 
 * Add fastpath handling of HLT VM-Exit to expedite re-entering the guest when
   there's already a pending wake event at the time of the exit.
 
 * Fix a WARN caused by RSM entering a nested guest from SMM with invalid guest
   state, by forcing the vCPU out of guest mode prior to signalling SHUTDOWN
   (the SHUTDOWN hits the VM altogether, not the nested guest)
 
 * Overhaul the "unprotect and retry" logic to more precisely identify cases
   where retrying is actually helpful, and to harden all retry paths against
   putting the guest into an infinite retry loop.
 
 * Add support for yielding, e.g. to honor NEED_RESCHED, when zapping rmaps in
   the shadow MMU.
 
 * Refactor pieces of the shadow MMU related to aging SPTEs in prepartion for
   adding multi generation LRU support in KVM.
 
 * Don't stuff the RSB after VM-Exit when RETPOLINE=y and AutoIBRS is enabled,
   i.e. when the CPU has already flushed the RSB.
 
 * Trace the per-CPU host save area as a VMCB pointer to improve readability
   and cleanup the retrieval of the SEV-ES host save area.
 
 * Remove unnecessary accounting of temporary nested VMCB related allocations.
 
 * Set FINAL/PAGE in the page fault error code for EPT violations if and only
   if the GVA is valid.  If the GVA is NOT valid, there is no guest-side page
   table walk and so stuffing paging related metadata is nonsensical.
 
 * Fix a bug where KVM would incorrectly synthesize a nested VM-Exit instead of
   emulating posted interrupt delivery to L2.
 
 * Add a lockdep assertion to detect unsafe accesses of vmcs12 structures.
 
 * Harden eVMCS loading against an impossible NULL pointer deref (really truly
   should be impossible).
 
 * Minor SGX fix and a cleanup.
 
 * Misc cleanups
 
 Generic:
 
 * Register KVM's cpuhp and syscore callbacks when enabling virtualization in
   hardware, as the sole purpose of said callbacks is to disable and re-enable
   virtualization as needed.
 
 * Enable virtualization when KVM is loaded, not right before the first VM
   is created.  Together with the previous change, this simplifies a
   lot the logic of the callbacks, because their very existence implies
   virtualization is enabled.
 
 * Fix a bug that results in KVM prematurely exiting to userspace for coalesced
   MMIO/PIO in many cases, clean up the related code, and add a testcase.
 
 * Fix a bug in kvm_clear_guest() where it would trigger a buffer overflow _if_
   the gpa+len crosses a page boundary, which thankfully is guaranteed to not
   happen in the current code base.  Add WARNs in more helpers that read/write
   guest memory to detect similar bugs.
 
 Selftests:
 
 * Fix a goof that caused some Hyper-V tests to be skipped when run on bare
   metal, i.e. NOT in a VM.
 
 * Add a regression test for KVM's handling of SHUTDOWN for an SEV-ES guest.
 
 * Explicitly include one-off assets in .gitignore.  Past Sean was completely
   wrong about not being able to detect missing .gitignore entries.
 
 * Verify userspace single-stepping works when KVM happens to handle a VM-Exit
   in its fastpath.
 
 * Misc cleanups

cb787f4ac0 [tree-wide] finally take no_llseek out
no_llseek had been defined to NULL two years ago, in commit 868941b144
("fs: remove no_llseek")

To quote that commit,

  At -rc1 we'll need do a mechanical removal of no_llseek -

  git grep -l -w no_llseek | grep -v porting.rst | while read i; do
	sed -i '/\<no_llseek\>/d' $i
  done

  would do it.

Unfortunately, that hadn't been done.  Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
	.llseek = no_llseek,
so it's obviously safe.

5e5466433d Char/Misc and other driver changes for 6.12-rc1
Here is the "big" set of char/misc and other driver subsystem changes
 for 6.12-rc1.  Sorry for the delay, conference travel for the past two
 weeks has this and my other pull requests showing up real late
 in the cycle.
 
 Lots of changes in here, primarily dominated by the usual IIO driver
 updates and additions, but there are also small driver subsystem updates
 all over the place.  Included in here are:
   - lots and lots of new IIO drivers and updates to existing ones
   - interconnect subsystem updates and new drivers
   - nvmem subsystem updates and new drivers
   - mhi driver updates
   - power supply subsystem updates
   - kobj_type const work for many different small subsystems
   - comedi driver fix
   - coresight subsystem and driver updates
   - fpga subsystem improvements
   - slimbus fixups
   - binder new feature addition for "frozen" notifications
   - lots and lots of other small driver updates and cleanups
 
 All of these have been in linux-next for a long time with no reported
 problems.

Here is the "big" set of tty/serial driver updates for 6.12-rc1.
 
 Nothing major in here, just nice forward progress in the slow cleanup of

 Included in here are:
   - serial api updates from Jiri to make things more uniform and sane
   - 8250_platform driver cleanups
   - samsung serial driver fixes and updates
   - qcom-geni serial driver fixes from Johan for the bizarre UART engine
     that that chip seems to have.  Hopefully it's in a better state now,
     but hardware designers still seem to come up with more ways to make
     broken UARTS 40+ years after this all should have finished.
   - sc16is7xx driver updates
   - omap 8250 driver updates
   - 8250_bcm2835aux driver updates
   - a few new serial driver bindings added
   - other serial minor driver updates

The iptables example was added in commit d2f26037a3 (netfilter: Add

option was added in commit a31e1ffd22 (netfilter: xt_socket: added new
revision of the 'socket' match supporting flags, 2009-06-09).

Now add the 'transparent' option to the iptables example to ignore
non-transparent sockets, which is also consistent with the nft example.

Toolchain and infrastructure:

    '___ADDRESSABLE()' for 'module_{init,exit}'. With that, we should be
    objtool-warning-free, so enable it to run for all Rust object files.
 
  - KASAN (no 'SW_TAGS'), KCFI and shadow call sanitizer support.
 
  - Support 'RUSTC_VERSION', including re-config and re-build on change.
 
  - Split helpers file into several files in a folder, to avoid conflicts
    in it. Eventually those files will be moved to the right places with
    the new build system. In addition, remove the need to manually export
    the symbols defined there, reusing existing machinery for that.
 
  - Relax restriction on configurations with Rust + GCC plugins to just
    the RANDSTRUCT plugin.
 
 'kernel' crate:
 
  - New 'list' module: doubly-linked linked list for use with reference
    counted values, which is heavily used by the upcoming Rust Binder.
    This includes 'ListArc' (a wrapper around 'Arc' that is guaranteed
    unique for the given ID), 'AtomicTracker' (tracks whether a 'ListArc'
    exists using an atomic), 'ListLinks' (the prev/next pointers for an
    item in a linked list), 'List' (the linked list itself), 'Iter' (an
    iterator over a 'List'), 'Cursor' (a cursor into a 'List' that allows
    to remove elements), 'ListArcField' (a field exclusively owned by a
    'ListArc'), as well as support for heterogeneous lists.
 
  - New 'rbtree' module: red-black tree abstractions used by the upcoming
    Rust Binder. This includes 'RBTree' (the red-black tree itself),
    'RBTreeNode' (a node), 'RBTreeNodeReservation' (a memory reservation
    for a node), 'Iter' and 'IterMut' (immutable and mutable iterators),
    'Cursor' (bidirectional cursor that allows to remove elements), as
    well as an entry API similar to the Rust standard library one.
 
  - 'init' module: add 'write_[pin_]init' methods and the 'InPlaceWrite'
    trait. Add the 'assert_pinned!' macro.
 
  - 'sync' module: implement the 'InPlaceInit' trait for 'Arc' by
    introducing an associated type in the trait.
 
  - 'alloc' module: add 'drop_contents' method to 'BoxExt'.
 
  - 'types' module: implement the 'ForeignOwnable' trait for
    'Pin<Box<T>>' and improve the trait's documentation. In addition,
    add the 'into_raw' method to the 'ARef' type.
 
  - 'error' module: in preparation for the upcoming Rust support for
    32-bit architectures, like arm, locally allow Clippy lint for those.
 
 Documentation:
 
  - https://rust.docs.kernel.org has been announced, so link to it.
 
  - Enable rustdoc's "jump to definition" feature, making its output a
    bit closer to the experience in a cross-referencer.
 
  - Debian Testing now also provides recent Rust releases (outside of
    the freeze period), so add it to the list.

79952bdcbc f2fs-6.12-rc1
In this series, the main changes include 1) converting major IO paths to use
 folio, and 2) adding various knobs to control GC more flexibly for Zoned
 devices. In addition, there are several patches to address corner cases of
 atomic file operations and better support for file pinning on zoned device.
 
 Enhancement:
  - add knobs to tune foreground/background GCs for Zoned devices
  - convert IO paths to use folio
  - reduce expensive checkpoint trigger frequency
  - allow F2FS_IPU_NOCACHE for pinned file
  - forcibly migrate to secure space for zoned device file pinning
  - get rid of buffer_head use
  - add write priority option based on zone UFS
  - get rid of online repair on corrupted directory
 
 Bug fix:
  - fix to don't panic system for no free segment fault injection
  - fix to don't set SB_RDONLY in f2fs_handle_critical_error()
  - avoid unused block when dio write in LFS mode
  - compress: don't redirty sparse cluster during {,de}compress
  - check discard support for conventional zones
  - atomic: prevent atomic file from being dirtied before commit
  - atomic: fix to check atomic_file in f2fs ioctl interfaces
  - atomic: fix to forbid dio in atomic_file
  - atomic: fix to truncate pagecache before on-disk metadata truncation
  - atomic: create COW inode from parent dentry
  - atomic: fix to avoid racing w/ GC
  - atomic: require FMODE_WRITE for atomic write ioctls
  - fix to wait page writeback before setting gcing flag
  - fix to avoid racing in between read and OPU dio write, dio completion
  - fix several potential integer overflows in file offsets and dir_block_index
  - fix to avoid use-after-free in f2fs_stop_gc_thread()
 
 As usual, there are several code clean-ups and refactorings.

5c480f1da8 remoteproc updates for v6.12
This adds remoteproc support for the Cortex M4F found in AM62x and AM64x
 of the TI K3 family, support for the modem remoteproc in the Qualcomm
 SDX75, and audio, compute and general-purpose DSPs of the Qualcomm
 SA8775P.
 
 The i.MX remoteproc driver gains support for blocking and non-blocking
 mailbox transmissions, followed by the implementation of poweroff and
 reboot mechanisms, using the same. This is followed by a few bug fixes
 and minor improvements.
 
 A few cleanups and bug fixes for the TI K3 DSP and R5F drivers are
 introduced.
 
 Support for mapping SRAM regions into the AMD-Xilinx Zynqmp R5 cores is
 added.
 
 The Ingenic, TI DA8xx, TI Keystone, TI K3, ST slim drivers are
 simplified using devres helpers for various allocations.
 
 Uses of of_{find,get}_property() are replaced with of_property_present()
 where possible.

9ab27b0186 The core clk framework is left largely untouched this time around except for
support for the newly ratified DT property 'assigned-clock-rates-u64'. I'm much
 more excited about the support for loading DT overlays from KUnit tests so that
 we can test how the clk framework parses DT nodes during clk registration. The
 clk framework has some places that are highly DeviceTree dependent so this
 charts the path to extend the KUnit tests to cover even more framework code in
 the future. I've got some more tests on the list that use the DT overlay
 support, but they uncovered issues with clk unregistration that I'm still
 working on fixing.
 
 Outside the core, the clk driver update pile is dominated by Qualcomm and
 Renesas SoCs, making it fairly usual. Looking closer, there are fixes for
 things all over the place, like adding missing clk frequencies or moving
 defines for the number of clks out of DT binding headers into the drivers.
 There are even conversions of DT bindings to YAML and migration away from
 strings to describe clk topology. Overall it doesn't look unusual so I expect
 the new drivers to be where we'll have fixes in the coming weeks.
 
 Core:
  - KUnit tests for clk registration and fixed rate basic clk type
  - A couple more devm helpers, one consumer and one provider
  - Support for assigned-clock-rates-u64
 
 New Drivers:
  - Camera, display and GPU clocks on Qualcomm SM4450
  - Camera clocks on Qualcomm SM8150
  - Rockchip rk3576 clks
  - Microchip SAM9X7 clks
  - Renesas RZ/V2H(P) (R9A09G057) clks
 
 Updates:
  - Mark a bunch of struct freq_tbl const to reduce .data usage
  - Add Qualcomm MSM8226 A7PLL and Regera PLL support
  - Fix the Qualcomm Lucid 5LPE PLL configuration sequence to not reuse
    Trion, as they do differ

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "The core clk framework is left largely untouched this time around
  except for support for the newly ratified DT property
  'assigned-clock-rates-u64'.

  I'm much more excited about the support for loading DT overlays from
  KUnit tests so that we can test how the clk framework parses DT nodes
  during clk registration. The clk framework has some places that are
  highly DeviceTree dependent so this charts the path to extend the
  KUnit tests to cover even more framework code in the future. I've got
  some more tests on the list that use the DT overlay support, but they
  uncovered issues with clk unregistration that I'm still working on
  fixing.

  Outside the core, the clk driver update pile is dominated by Qualcomm
  and Renesas SoCs, making it fairly usual. Looking closer, there are
  fixes for things all over the place, like adding missing clk
  frequencies or moving defines for the number of clks out of DT binding
  headers into the drivers. There are even conversions of DT bindings to
  YAML and migration away from strings to describe clk topology. Overall
  it doesn't look unusual so I expect the new drivers to be where we'll
  have fixes in the coming weeks.

  Core:
   - KUnit tests for clk registration and fixed rate basic clk type
   - A couple more devm helpers, one consumer and one provider
   - Support for assigned-clock-rates-u64

  New Drivers:
   - Camera, display and GPU clocks on Qualcomm SM4450
   - Camera clocks on Qualcomm SM8150
   - Rockchip rk3576 clks
   - Microchip SAM9X7 clks
   - Renesas RZ/V2H(P) (R9A09G057) clks

  Updates:
   - Mark a bunch of struct freq_tbl const to reduce .data usage
   - Add Qualcomm MSM8226 A7PLL and Regera PLL support
   - Fix the Qualcomm Lucid 5LPE PLL configuration sequence to not reuse
     Trion, as they do differ
   - A number of fixes to the Qualcomm SM8550 display clock driver
   - Fold Qualcomm SM8650 display clock driver into SM8550 one

4e2c9cd7dc i2c-for-6.12-rc1
I2C core
 ========
 
 After 15 years of deprecation, the I2C_COMPAT symbol has finally been
 removed. Also client addresses are now locked during initialization to
 prevent race conditions between different kinds of instantiation. Scoped
 foreach OF child loops are now used. And the testunit has received some
 cleanups and documentation improvements as well as two new tests, one
 for repeated start and one for triggering SMBusAlert interrupts.
 
 I2C host drivers
 ================
 
 The DesignWare and the Renesas I2C drivers have received most of
 the changes in this pull request.
 
 The first has has undergone through a series of cleanups that
 have been sent to the mailing list a year ago for the first time
 and finally get merged in this pull request. They are many, from
 typos (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move
 inline functions to librarieas) and many others.
 
 Besides that, all the DesignWare Kconfig options have been
 grouped under the I2C_DESIGNWARE_CORE and this required some
 adaptation in many of the kernel configuration files for
 different arm and mips boards.
 
 Follows the list of the rest of the changes grouped by type of
 change.
 
 Cleanups
 --------
 The Qualcomm Geni platform improves the exit path in the runtime
 resume function.
 
 The Intel LJCA driver loses "target_addr" parameter in
 ljca_i2c_stop() because it was unused.
 
 The MediaTek controller intializes the restart_flag in the
 transfer function using the ternary conditional operator ("? :")
 instead of initializing it in different parts.
 
 Constified a few global data structures in the virtio driver.
 
 The Renesas driver simplifies the bus speed handling in the init
 function making it more readable.
 
 Improved an if/else statement in probe function of the Renesas
 R-Car driver.
 
 The iMX/MXC driver switches to using the RUNTIME_PM_OPS() instead
 of SET_RUNTIME_PM_OPS().
 
 Still in the iMX/MXC driver a comma ',' has been replaced by a
 semicolon ';', while in different drivers the ',' has been
 removed from the '{ }' delimiters.
 
 Finally three devm_clk_get_enabled() have been used to simplify
 the devm_clk_get/clk_prepare_enable tuple in the Renesas EMEV2,
 Ingenic and MPC drivers.
 
 Refactors
 ---------
 The Nuvoton fixes a potential out of boundary array access. This
 is not a bug fix because the issue could never occur due to
 hardware not having the properties listed in the array. The
 change makes the driver more future proof and, at the same time,
 silences code analyzers.
 
 Improvements
 ------------
 The Renesas I2C (riic) driver undergoes several patches improving
 the runtime power management handling.
 
 The Intel i801 driver uses a more descriptive adapter's name to
 show the presence of the IDF feature.
 
 In the Intel Denverton (ismt) adapter the pending transactions
 are killed when irq's can't complete their handling, triggering a
 timeout. This could have been considered as a bug fix, but
 because, standing to Vasily, it's very sporadic, I preferred
 considering the patch rather as an improvement.
 
 New Feature
 -----------
 The Renesas I2C (riic) driver now supports the fast mode plus.
 
 New support
 -----------
 Added support for:
 
     - Renesas R9A08G045
     - Rockchip RK3576
     - KEBA I2C
     - Theobroma Systems Mule Multiplexer.
 
 The Keba comes with a new driver, i2c-keba.c.
 The Mule is an i2c multiplexer and it also comes with a new
 driver, mux/i2c-mux-mule.c.
 
 Core patch
 ----------
 This pull request includes also a patch in the I2C framework, in
 i2c-core-base.c where the runtime PM functions have been replaced
 in order to allow to be accessed during the device add.
 
 Devicetree
 ----------
 Some cleanups in the devicetree, as well. nVidia and Qualcomm
 bindings improve their "if:then:" blocks. While the aspeed
 binding loses the "multi-master" property because it was
 redundant.
 
 The i2c-sprd binding has been converted to YAML.

d7dfb07d4d firewire updates for v6.12
The batch of changes includes the followwing:
 
 - Replacing tasklet with usual workqueue for isochronous context
 - Replacing IDR with XArray
 - Utilizing guard macro where possible
 - Printing deprecation warning when enabling debug parameter of
   firewire-ohci module
 
 Additionally, it includes a single patch for sound subsystem which the
 subsystem maintainer acked:
 
 - Switching to nonatomic PCM operation
 
 In FireWire subsystem, tasklet has been used as the bottom half of 1394
 OHCi hardIRQ so long. In the recent kernel updates, BH workqueue has
 been available, and some developers have proposed replacing tasklet with
 BH workqueue. While it is fortunate that developers are still considering
 the legacy subsystem, a simple replacement is not necessarily suitable.
 
 As a first step towards dropping tasklet, I've investigated the
 feasibility for 1394 OHCI isochronous context, and concluded that usual
 workqueue is available. In the context, the batch of packets is processed
 in the specific queue, thus the timing jitter caused by task scheduling is
 not so critical. Additionally, DMA transmission can be scheduled
 per-packet basis, therefore the context can be sleep between the operation
 of transmissions. Furthermore, in-kernel protocol implementation involves
 some CPU-bound tasks, which can sometimes consumes CPU time so long. These
 characteristics suggest that usual workqueue is suitable, through BH
 workqueues are not.
 
 The replacement with usual workqueue allows unit drivers to process the
 content of packets in non-atomic context. It brings some reliefs to some
 drivers in sound subsystem that spin-lock is not mandatory anymore during
 isochronous packet processing.

Pull firewire updates from Takashi Sakamoto:
 "In the FireWire subsystem, tasklets have been used as the bottom half
  of 1394 OHCi hardIRQ. In recent kernel updates, BH workqueues have
  become available, and some developers have proposed replacing the
  tasklet with a BH workqueue.

  As a first step towards dropping tasklet use, the 1394 OHCI
  isochronous context can use regular workqueues. In this context, the
  batch of packets is processed in the specific queue, thus the timing
  jitter caused by task scheduling is not so critical.

  Additionally, DMA transmission can be scheduled per-packet basis,
  therefore the context can be sleep between the operation of
  transmissions. Furthermore, in-kernel protocol implementation involves
  some CPU-bound tasks, which can sometimes consumes CPU time so long.
  These characteristics suggest that normal workqueues are suitable,
  through BH workqueues are not.

  The replacement with a workqueue allows unit drivers to process the
  content of packets in non-atomic context. It brings some reliefs to
  some drivers in sound subsystem that spin-lock is not mandatory
  anymore during isochronous packet processing.

  Summary:

   - Replace tasklet with workqueue for isochronous context

   - Replace IDR with XArray

   - Utilize guard macro where possible

   - Print deprecation warning when enabling debug parameter of
     firewire-ohci module

   - Switch to nonatomic PCM operation"

 "Enumeration:

   - Wait for device readiness after reset by polling Vendor ID and

736cd2c1ae nfs: add "NFS Client and Server Interlock" section to localio.rst
This section answers a new FAQ entry:

9. How does LOCALIO make certain that object lifetimes are managed
   properly given NFSD and NFS operate in different contexts?

   See the detailed "NFS Client and Server Interlock" section below.

The first half of the section details NeilBrown's elegant design
for LOCALIO's nfs_uuid_t based interlock and is heavily based on
Neil's "net namespace refcounting" description here:
  https://marc.info/?l=linux-nfs&m=172498546024767&w=2

The second half of the section details the per-cpu-refcount introduced
to ensure NFSD's nfsd_serv isn't destroyed while in use by a LOCALIO
client.

This document gives an overview of the LOCALIO auxiliary RPC protocol
added to the Linux NFS client and server to allow them to reliably
handshake to determine if they are on the same host.

Once an NFS client and server handshake as "local", the client will
bypass the network RPC protocol for read, write and commit operations.
Due to this XDR and RPC bypass, these operations will operate faster.

2eb5d7f242 kbuild: doc: describe the -C option precisely for external module builds
Building external modules is typically done using this command:

  $ make -C <KERNEL_DIR> M=<EXTMOD_DIR>

Here, <KERNEL_DIR> refers to the output directory where the kernel was
built, not the kernel source directory.

When the kernel is built in the source tree, there is no ambiguity, as
the output directory and the source directory are the same.

If the kernel was built in a separate build directory, <KERNEL_DIR>
should be the kernel output directory. Otherwise, Kbuild cannot locate
necessary build artifacts. This has been the method for building
external modules against a pre-built kernel in a separate directory
for over 20 years. [1]

If you pass the kernel source directory to the -C option, you must also
specify the kernel build directory using the O= option. This approach
works as well, though it results in a slightly longer command:

  $ make -C <KERNEL_SOURCE_DIR> O=<KERNEL_BUILD_DIR> M=<EXTMOD_DIR>

Some people mistakenly believe that O= should specify a build directory
for external modules when used together with M=. This commit adds more
clarification to Documentation/kbuild/kbuild.rst.

 "subvolume_get_snapshot()" and also fixing another source of srcu lock
 time warnings, by running each loop iteration in its own transaction (as
 the existing for_each_btree_key() does).
 
 More work on btree_trans locking asserts; we now assert that we don't
 hold btree node locks when trans->locked is false, which is important
 because we don't use lockdep for tracking individual btree node locks.
 
 Some cleanups and improvements in the bset.c btree node lookup code,
 from Alan.
 
 Rework of btree node pinning, which we use in backpointers fsck. The old
 hacky implementation, where the shrinker just skipped over nodes in the
 pinned range, was causing OOMs; instead we now use another shrinker with
 a much higher seeks number for pinned nodes.
 
 Rebalance now uses BCH_WRITE_ONLY_SPECIFIED_DEVS; this fixes an issue
 where rebalance would sometimes fall back to allocating from the full
 filesystem, which is not what we want when it's trying to move data to a
 specific target.
 
 Use __GFP_ACCOUNT, GFP_RECLAIMABLE for btree node, key cache
 allocations.
 
 Idmap mounts are now supported - Hongbo.
 
 Rename whiteouts are now supported - Hongbo.
 
 Erasure coding can now handle devices being marked as failed, or
 forcibly removed. We still need the evacuate path for erasure coding,
 but it's getting very close to ready for people to start using.
 
 Status, and when will we be taking off experimental:
 ----------------------------------------------------
 
 Going by critical, user facing bugs getting found and fixed, we're
 nearly there. There are a couple key items that need to be finished
 before we can take off the experimental label:
 
 - The end-user experience is still pretty painful when the root
   filesystem needs a fsck; we need some form of limited self healing so
   that necessary repair gets run automatically. Errors (by type) are
   recorded in the superblock, so what we need to do next is convert
   remaining inconsistent() errors to fsck() errors (so that all runtime
   inconsistencies are logged in the superblock), and we need to go
   through the list of fsck errors and classify them by which fsck passes
   are needed to repair them.
 
 - We need comprehensive torture testing for all our repair paths, to
   shake out remaining bugs there. Thomas has been working on the tooling
   for this, so this is coming soonish.
 
 Slightly less critical items:
 
 - We need to improve the end-user experience for degraded mounts: right
   now, a degraded root filesystem means dropping to an initramfs shell
   or somehow inputting mount options manually (we don't want to allow
   degraded mounts without some form of user input, except on unattended
   servers) - we need the mount helper to prompt the user to allow
   mounting degraded, and make sure this works with systemd.
 
 - Scalabiity: we have users running 100TB+ filesystems, and that's
   effectively the limit right now due to fsck times. We have some
   reworks in the pipeline to address this, we're aiming to make petabyte
   sized filesystems practical.

Pull bcachefs updates from Kent Overstreet:

 - rcu_pending, btree key cache rework: this solves lock contenting in
   the key cache, eliminating the biggest source of the srcu lock hold
   time warnings, and drastically improving performance on some metadata
   heavy workloads - on multithreaded creates we're now 3-4x faster than
   xfs.

   this is another significant performance improvement on multithreaded
   metadata workloads, eliminating more lock contention.

431844b65f sched_ext: Provide a sysfs enable_seq counter
As discussed during the distro-centric session within the sched_ext
Microconference at LPC 2024, introduce a sequence counter that is
incremented every time a BPF scheduler is loaded.

This feature can help distributions in diagnosing potential performance
regressions by identifying systems where users are running (or have ran)
custom BPF schedulers.

Example:

 arighi@virtme-ng~> cat /sys/kernel/sched_ext/enable_seq
 0
 arighi@virtme-ng~> sudo scx_simple
 local=1 global=0
 ^CEXIT: unregistered from user space
 arighi@virtme-ng~> cat /sys/kernel/sched_ext/enable_seq
 1

In this way user-space tools (such as Ubuntu's apport and similar) are
able to gather and include this information in bug reports.

Linus Torvalds
af9c191ac2 ring-buffer: Updates for v6.12:
- Merged v6.11-rc3 into trace/ring-buffer/core
 
   The v6.10 ring buffer pull request was not made due to Mathieu Desnoyers
   making a comment to the pull request. Mathieu and I resolved it on IRC,
   but we did not let Linus know that it was resolved. Linus did not do the
   pull thinking it still had some unresolved issues.
 
   The ring buffer work for 6.12 was dependent on both this pull request as
   well as the reserve_mem kernel command line option that was going upstream
   through the memory management tree. The ring buffer repo was being used by
   others so it could not be rebased. In order to continue the work, the
   v6.11-rc3 branch was pulled in to get access to the reserve_mem work.
 
 This has the 6.11 pull request that did not make it into 6.11, which was:
 
   tracing/ring-buffer: Have persistent buffer across reboots
 
   This allows for the tracing instance ring buffer to stay persistent across
   reboots. The way this is done is by adding to the kernel command line:
 
     trace_instance=boot_map@0x285400000:12M
 
   This will reserve 12 megabytes at the address 0x285400000, and then map
   the tracing instance "boot_map" ring buffer to that memory. This will
   appear as a normal instance in the tracefs system:
 
     /sys/kernel/tracing/instances/boot_map
 
   A user could enable tracing in that instance, and on reboot or kernel
   crash, if the memory is not wiped by the firmware, it will recreate the
   trace in that instance. For example, if one was debugging a shutdown of a
   kernel reboot:
 
    # cd /sys/kernel/tracing
    # echo function > instances/boot_map/current_tracer
    # reboot
   [..]
    # cd /sys/kernel/tracing
    # tail instances/boot_map/trace

          swapper/0-1       [000] d..1.   164.549822: acpi_os_write_port <-acpi_reboot
 
   On reboot, the buffer is examined to make sure it is valid. The validation
   check even steps through every event to make sure the meta data of the
   event is correct. If any test fails, it will simply reset the buffer, and
   the buffer will be empty on boot.
 
 The new changes for 6.12 are:
 
 - Allow the tracing persistent boot buffer to use the "reserve_mem" option
 
   Instead of having the admin find a physical address to store the persistent
   buffer, which can be very tedious if they have to administrate several
   different machines, allow them to use the "reserve_mem" option that will
   find a location for them. It is not as reliable because of KASLR, as the
   loading of the kernel in different locations can cause the memory
   allocated to be inconsistent. Booting with "nokaslr" can make reserve_mem
   more reliable.
 
 - Have function graph tracer handle offsets from a previous boot.
 
   The ring buffer output from a previous boot may have different addresses
   due to kaslr. Have the function graph tracer handle these by using the
   delta from the previous boot to the new boot address space.
 
 - Only reset the saved meta offset when the buffer is started or reset
 
   In the persistent memory meta data, it holds the previous address space
   information, so that it can calculate the delta to have function tracing
   work. But this gets updated after being read to hold the new address
   space. But if the buffer isn't used for that boot, on reboot, the delta is
   now calculated from the previous boot and not the boot that holds the data
   in the ring buffer. This causes the functions not to be shown. Do not save
   the address space information of the current kernel until it is being
   recorded.
 
 - Add a magic variable to test the valid meta data
 
   Add a magic variable in the meta data that can also be used for
   validation. The validator of the previous buffer doesn't need this magic
   data, but it can be used if the meta data is changed by a new kernel, which
   may have the same format that passes the validator but is used
   differently. This magic number can also be used as a "versioning" of the
   meta data.
 
 - Align user space mapped ring buffer sub buffers to improve TLB entries
 
   Linus mentioned that the mapped ring buffer sub buffers were misaligned
   between the meta page and the sub-buffers, so that if the sub-buffers were
   bigger than PAGE_SIZE, it wouldn't allow the TLB to use bigger entries.
 
 - Add new kernel command line "traceoff" to disable tracing on boot for instances
 
   If tracing is enabled for a boot instance, there needs a way to be able to
   disable it on boot so that new events do not get entered into the ring
   buffer and be mixed with events from a previous boot, as that can be
   confusing.
 
 - Allow trace_printk() to go to other instances
 
   Currently, trace_printk() can only go to the top level instance. When
   debugging with a persistent buffer, it is really useful to be able to add
   trace_printk() to go to that buffer, so that you have access to them after
   a crash.
 
 - Do not use "bin_printk()" for traces to a boot instance
 
   The bin_printk() saves only a pointer to the printk format in the ring
   buffer, as the reader of the buffer can still have access to it. But this
   is not the case if the buffer is from a previous boot. If the
   trace_printk() is going to a "persistent" buffer, it will use the slower
   version that writes the printk format into the buffer.
 
 - Add command line option to allow trace_printk() to go to an instance
 
   Allow the kernel command line to define which instance the trace_printk()
   goes to, instead of forcing the admin to set it for every boot via the
   tracefs options.
 
 - Start a document that explains how to use tracefs to debug the kernel
 
 - Add some more kernel selftests to test user mapped ring buffer

   On reboot, the buffer is examined to make sure it is valid. The
   validation check even steps through every event to make sure the meta
   data of the event is correct. If any test fails, it will simply reset
   the buffer, and the buffer will be empty on boot.

 - Allow the tracing persistent boot buffer to use the "reserve_mem"
   option

   Instead of having the admin find a physical address to store the
   persistent buffer, which can be very tedious if they have to
   administrate several different machines, allow them to use the
   "reserve_mem" option that will find a location for them. It is not as
   reliable because of KASLR, as the loading of the kernel in different
   locations can cause the memory allocated to be inconsistent. Booting
   with "nokaslr" can make reserve_mem more reliable.

 - Have function graph tracer handle offsets from a previous boot.

   The ring buffer output from a previous boot may have different
   addresses due to kaslr. Have the function graph tracer handle these
   by using the delta from the previous boot to the new boot address
   space.

 - Only reset the saved meta offset when the buffer is started or reset

   In the persistent memory meta data, it holds the previous address
   space information, so that it can calculate the delta to have
   function tracing work. But this gets updated after being read to hold
   the new address space. But if the buffer isn't used for that boot, on
   reboot, the delta is now calculated from the previous boot and not
   the boot that holds the data in the ring buffer. This causes the
   functions not to be shown. Do not save the address space information
   of the current kernel until it is being recorded.

 - Add a magic variable to test the valid meta data

   Add a magic variable in the meta data that can also be used for
   validation. The validator of the previous buffer doesn't need this
   magic data, but it can be used if the meta data is changed by a new
   kernel, which may have the same format that passes the validator but
   is used differently. This magic number can also be used as a
   "versioning" of the meta data.

 - Align user space mapped ring buffer sub buffers to improve TLB
   entries

   Linus mentioned that the mapped ring buffer sub buffers were
   misaligned between the meta page and the sub-buffers, so that if the
   sub-buffers were bigger than PAGE_SIZE, it wouldn't allow the TLB to
   use bigger entries.

 - Add new kernel command line "traceoff" to disable tracing on boot for
   instances

   If tracing is enabled for a boot instance, there needs a way to be
   able to disable it on boot so that new events do not get entered into
   the ring buffer and be mixed with events from a previous boot, as
   that can be confusing.

 - Allow trace_printk() to go to other instances

   Currently, trace_printk() can only go to the top level instance. When
   debugging with a persistent buffer, it is really useful to be able to
   add trace_printk() to go to that buffer, so that you have access to
   them after a crash.

 - Do not use "bin_printk()" for traces to a boot instance

   The bin_printk() saves only a pointer to the printk format in the
   ring buffer, as the reader of the buffer can still have access to it.
   But this is not the case if the buffer is from a previous boot. If
   the trace_printk() is going to a "persistent" buffer, it will use the
   slower version that writes the printk format into the buffer.

 - Add command line option to allow trace_printk() to go to an instance

   Allow the kernel command line to define which instance the
   trace_printk() goes to, instead of forcing the admin to set it for
   every boot via the tracefs options.

 - Start a document that explains how to use tracefs to debug the kernel

 - Add some more kernel selftests to test user mapped ring buffer

88264981f2 sched_ext: Initial pull request for v6.12
This is the initial pull request of sched_ext. The v7 patchset
 (https://lkml.kernel.org/r/20240618212056.2833381-1-tj@kernel.org) is
 applied on top of tip/sched/core + bpf/master as of Jun 18th.
 
   tip/sched/core 793a62823d1c ("sched/core: Drop spinlocks on contention iff kernel is preempti
 ble")
   bpf/master f6afdaf72a ("Merge branch 'bpf-support-resilient-split-btf'")
 
 Since then, the following pulls were made:
 
 - v6.11-rc1 is pulled to keep up with the mainline.
 
 - tip/sched/core was pulled several times:
 
   - 7b9f6c864a, 0df340ceae, 5ac998574f, 0b1777f0fa: To resolve
     conflicts. See each commit for details on conflicts and their
     resolutions.
 
   - d7b01aef9d: To receive fd03c5b858 ("sched: Rework pick_next_task()")
     and related commits. @prev in added to sched_class->put_prev_task() and
     put_prev_task() is reordered after ->pick_task(), which makes
     sched_class->switch_class() unnecessary. The follow-up commits update
     sched_ext accordingly and drop sched_class->switch_class().
 
 - bpf/master was pulled to receive baebe9aaba ("bpf: allow passing struct
   bpf_iter_<type> as kfunc arguments") and related changes in preparation
   for the DSQ iterator patchset
 
 To obtain the net sched_ext changes, diff against:
 
   git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext.git for-6.12-base
 
 which is the merge of:
 
   tip/sched/core bc9057da1a ("sched/cpufreq: Use NSEC_PER_MSEC for deadline task")
   bpf/master 2ad6d23f46 ("selftests/bpf: Do not update vmlinux.h unnecessarily")
 
 Since the v7 patchset, the following changes were made:
 
 - cpuperf support which was a part of the v6 patchset was posted separately
   and then applied after reviews.
 
 - cgroup support which was a part of the v6 patchset was posted seprately,
   iterated and then applied.
 
 - Improve integration with sched core.
 
 - Double locking usage in migration paths dropped. Depend on
   TASK_ON_RQ_MIGRATING synchronization instead.
 
 - The BPF scheduler couldn't directly dispatch to the local DSQ of another
   CPU using a SCX_DSQ_LOCAL_ON verdict. This caused difficulties around
   handling non-wakeup enqueues. Updated so that SCX_DSQ_LOCAL_ON can be used
   in the enqueue path too.
 
 - DSQ iterator which was a part of the v6 patchset was posted separately.
   The iterator itself was applied after a couple revisions. The associated
   selective consumption kfunc can use further improvements and is still
   being worked on.
 
 - scx_bpf_dispatch[_vtime]_from_dsq() added to increase flexibility. A task
   can now be transferred between two DSQs from almost any context. This
   involved significant refactoring of migration code.
 
 - Various fixes and improvements.
 
 As the branch is based on top of tip/sched/core + bpf/master, please merge
 after both are applied.

Merge tag 'sched_ext-for-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext

Pull sched_ext support from Tejun Heo:
 "This implements a new scheduler class called ‘ext_sched_class’, or
  sched_ext, which allows scheduling policies to be implemented as BPF
  programs.

  The goals of this are:

   - Ease of experimentation and exploration: Enabling rapid iteration
     of new scheduling policies.

   - Customization: Building application-specific schedulers which
     implement policies that are not applicable to general-purpose
     schedulers.

   - Rapid scheduler deployments: Non-disruptive swap outs of scheduling
     policies in production environments"

See individual commits for more documentation, but also the cover letter
for the latest series:

Merge tag 'bpf-next-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next

Pull bpf updates from Alexei Starovoitov:

 - Introduce '__attribute__((bpf_fastcall))' for helpers and kfuncs with
   corresponding support in LLVM.

   It is similar to existing 'no_caller_saved_registers' attribute in
   GCC/LLVM with a provision for backward compatibility. It allows
   compilers generate more efficient BPF code assuming the verifier or
   JITs will inline or partially inline a helper/kfunc with such
   attribute. bpf_cast_to_kern_ctx, bpf_rdonly_cast,
   bpf_get_smp_processor_id are the first set of such helpers.

 - Harden and extend ELF build ID parsing logic.

   When called from sleepable context the relevants parts of ELF file
   will be read to find and fetch .note.gnu.build-id information. Also
   harden the logic to avoid TOCTOU, overflow, out-of-bounds problems.

 - Improvements and fixes for sched-ext:
    - Allow passing BPF iterators as kfunc arguments
    - Make the pointer returned from iter_next method trusted
    - Fix x86 JIT convergence issue due to growing/shrinking conditional
      jumps in variable length encoding

 - BPF_LSM related:
    - Introduce few VFS kfuncs and consolidate them in
      fs/bpf_fs_kfuncs.c
    - Enforce correct range of return values from certain LSM hooks
    - Disallow attaching to other LSM hooks

 - Prerequisite work for upcoming Qdisc in BPF:
    - Allow kptrs in program provided structs
    - Support for gen_epilogue in verifier_ops

 - Important fixes:
    - Fix uprobe multi pid filter check
    - Fix bpf_strtol and bpf_strtoul helpers
    - Track equal scalars history on per-instruction level
    - Fix tailcall hierarchy on x86 and arm64
    - Fix signed division overflow to prevent INT_MIN/-1 trap on x86
    - Fix get kernel stack in BPF progs attached to tracepoint:syscall

 - Selftests:
    - Add uprobe bench/stress tool
    - Generate file dependencies to drastically improve re-build time
    - Match JIT-ed and BPF asm with __xlated/__jited keywords
    - Convert older tests to test_progs framework
    - Add support for RISC-V
    - Few fixes when BPF programs are compiled with GCC-BPF backend
      (support for GCC-BPF in BPF CI is ongoing in parallel)
    - Add traffic monitor
    - Enable cross compile and musl libc

 "nilfs2: add support for some common ioctls" from Ryusuke Konishi.  Adds
 various commonly-available ioctls to nilfs2.
 
 "This series fixes a number of formatting issues in kernel doc comments"
 from Ryusuke Konishi does that.

this pull request are:
 
 "Align kvrealloc() with krealloc()" from Danilo Krummrich.  Adds
 consistency to the APIs and behaviour of these two core allocation
 functions.  This also simplifies/enables Rustification.
 
 "Some cleanups for shmem" from Baolin Wang.  No functional changes - mode
 code reuse, better function naming, logic simplifications.
 
 "mm: some small page fault cleanups" from Josef Bacik.  No functional
 changes - code cleanups only.
 
 "Various memory tiering fixes" from Zi Yan.  A small fix and a little
 cleanup.
 
 "mm/swap: remove boilerplate" from Yu Zhao.  Code cleanups and
 simplifications and .text shrinkage.
 
 "Kernel stack usage histogram" from Pasha Tatashin and Shakeel Butt.  This
 is a feature, it adds new feilds to /proc/vmstat such as
 
     $ grep kstack /proc/vmstat
     kstack_1k 3
     kstack_2k 188
     kstack_4k 11391
     kstack_8k 243
     kstack_16k 0
 
 which tells us that 11391 processes used 4k of stack while none at all
 used 16k.  Useful for some system tuning things, but partivularly useful
 for "the dynamic kernel stack project".
 
 "kmemleak: support for percpu memory leak detect" from Pavel Tikhomirov.
 Teaches kmemleak to detect leaksage of percpu memory.
 
 "mm: memcg: page counters optimizations" from Roman Gushchin.  "3
 independent small optimizations of page counters".
 
 "mm: split PTE/PMD PT table Kconfig cleanups+clarifications" from David
 Hildenbrand.  Improves PTE/PMD splitlock detection, makes powerpc/8xx work
 correctly by design rather than by accident.
 
 "mm: remove arch_make_page_accessible()" from David Hildenbrand.  Some
 folio conversions which make arch_make_page_accessible() unneeded.
 
 "mm, memcg: cg2 memory{.swap,}.peak write handlers" fro David Finkel.
 Cleans up and fixes our handling of the resetting of the cgroup/process
 peak-memory-use detector.
 
 "Make core VMA operations internal and testable" from Lorenzo Stoakes.
 Rationalizaion and encapsulation of the VMA manipulation APIs.  With a
 view to better enable testing of the VMA functions, even from a

 some missing info in /proc/zoneinfo.
 
 "mm: replace follow_page() by folio_walk" from David Hildenbrand.  Code
 cleanups and rationalizations (conversion to folio_walk()) resulting in
 the removal of follow_page().
 
 "improving dynamic zswap shrinker protection scheme" from Nhat Pham.  Some
 tuning to improve zswap's dynamic shrinker.  Significant reductions in
 swapin and improvements in performance are shown.
 
 "mm: Fix several issues with unaccepted memory" from Kirill Shutemov.
 Improvements to the new unaccepted memory feature,
 
 "mm/mprotect: Fix dax puds" from Peter Xu.  Implements mprotect on DAX
 PUDs.  This was missing, although nobody seems to have notied yet.
 
 "Introduce a store type enum for the Maple tree" from Sidhartha Kumar.
 Cleanups and modest performance improvements for the maple tree library
 code.
 
 "memcg: further decouple v1 code from v2" from Shakeel Butt.  Move more
 cgroup v1 remnants away from the v2 memcg code.
 
 "memcg: initiate deprecation of v1 features" from Shakeel Butt.  Adds
 various warnings telling users that memcg v1 features are deprecated.

 improves the performance of munmap() of swap-filled ptes.
 
 "support large folio swap-out and swap-in for shmem" from Baolin Wang.
 With this series we no longer split shmem large folios into simgle-page
 folios when swapping out shmem.
 
 "mm/hugetlb: alloc/free gigantic folios" from Yu Zhao.  Nice performance
 improvements and code reductions for gigantic folios.
 
 "support shmem mTHP collapse" from Baolin Wang.  Adds support for
 khugepaged's collapsing of shmem mTHP folios.

c24999e61b The DesignWare and the Renesas I2C drivers have received most of
the changes in this pull request.
 
 The first has has undergone through a series of cleanups that
 have been sent to the mailing list a year ago for the first time
 and finally get merged in this pull request. They are many, from
 typos (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move
 inline functions to librarieas) and many others.
 
 Besides that, all the DesignWare Kconfig options have been
 grouped under the I2C_DESIGNWARE_CORE and this required some
 adaptation in many of the kernel configuration files for
 different arm and mips boards.
 
 Follows the list of the rest of the changes grouped by type of
 change.
 
 Cleanups
 --------
 The Qualcomm Geni platform improves the exit path in the runtime
 resume function.
 
 The Intel LJCA driver loses "target_addr" parameter in
 ljca_i2c_stop() because it was unused.
 
 The MediaTek controller intializes the restart_flag in the
 transfer function using the ternary conditional operator ("? :")
 instead of initializing it in different parts.
 
 Constified a few global data structures in the virtio driver.
 
 The Renesas driver simplifies the bus speed handling in the init
 function making it more readable.
 
 Improved an if/else statement in probe function of the Renesas
 R-Car driver.
 
 The iMX/MXC driver switches to using the RUNTIME_PM_OPS() instead
 of SET_RUNTIME_PM_OPS().
 
 Still in the iMX/MXC driver a comma ',' has been replaced by a
 semicolon ';', while in different drivers the ',' has been
 removed from the '{ }' delimiters.
 
 Finally three devm_clk_get_enabled() have been used to simplify
 the devm_clk_get/clk_prepare_enable tuple in the Renesas EMEV2,
 Ingenic and MPC drivers.
 
 Refactors
 ---------
 The Nuvoton fixes a potential out of boundary array access. This
 is not a bug fix because the issue could never occur due to
 hardware not having the properties listed in the array. The
 change makes the driver more future proof and, at the same time,
 silences code analyzers.
 
 Improvements
 ------------
 The Renesas I2C (riic) driver undergoes several patches improving
 the runtime power management handling.
 
 The Intel i801 driver uses a more descriptive adapter's name to
 show the presence of the IDF feature.
 
 In the Intel Denverton (ismt) adapter the pending transactions
 are killed when irq's can't complete their handling, triggering a
 timeout. This could have been considered as a bug fix, but
 because, standing to Vasily, it's very sporadic, I preferred
 considering the patch rather as an improvement.
 
 New Feature
 -----------
 The Renesas I2C (riic) driver now supports the fast mode plus.
 
 New support
 -----------
 Added support for:
 
     - Renesas R9A08G045
     - Rockchip RK3576
     - KEBA I2C
     - Theobroma Systems Mule Multiplexer.
 
 The Keba comes with a new driver, i2c-keba.c.
 The Mule is an i2c multiplexer and it also comes with a new
 driver, mux/i2c-mux-mule.c.

Merge tag 'i2c-host-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-mergewindow

The DesignWare and the Renesas I2C drivers have received most of
the changes in this pull request.

The first has has undergone through a series of cleanups that
have been sent to the mailing list a year ago for the first time
and finally get merged in this pull request. They are many, from
typos (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move
inline functions to librarieas) and many others.

Besides that, all the DesignWare Kconfig options have been
grouped under the I2C_DESIGNWARE_CORE and this required some
adaptation in many of the kernel configuration files for
different arm and mips boards.

Follows the list of the rest of the changes grouped by type of
change.

Cleanups
--------
The Qualcomm Geni platform improves the exit path in the runtime
resume function.

The Intel LJCA driver loses "target_addr" parameter in
ljca_i2c_stop() because it was unused.

The MediaTek controller intializes the restart_flag in the
transfer function using the ternary conditional operator ("? :")
instead of initializing it in different parts.

Constified a few global data structures in the virtio driver.

The Renesas driver simplifies the bus speed handling in the init
function making it more readable.

Improved an if/else statement in probe function of the Renesas
R-Car driver.

The iMX/MXC driver switches to using the RUNTIME_PM_OPS() instead
of SET_RUNTIME_PM_OPS().

Still in the iMX/MXC driver a comma ',' has been replaced by a
semicolon ';', while in different drivers the ',' has been
removed from the '{ }' delimiters.

Finally three devm_clk_get_enabled() have been used to simplify
the devm_clk_get/clk_prepare_enable tuple in the Renesas EMEV2,
Ingenic and MPC drivers.

Refactors
---------
The Nuvoton fixes a potential out of boundary array access. This
is not a bug fix because the issue could never occur due to
hardware not having the properties listed in the array. The
change makes the driver more future proof and, at the same time,
silences code analyzers.

Improvements
------------
The Renesas I2C (riic) driver undergoes several patches improving
the runtime power management handling.

The Intel i801 driver uses a more descriptive adapter's name to
show the presence of the IDF feature.

In the Intel Denverton (ismt) adapter the pending transactions
are killed when irq's can't complete their handling, triggering a
timeout. This could have been considered as a bug fix, but
because, standing to Vasily, it's very sporadic, I preferred
considering the patch rather as an improvement.

New Feature
-----------
The Renesas I2C (riic) driver now supports the fast mode plus.

New support
-----------
Added support for:

    - Renesas R9A08G045
    - Rockchip RK3576
    - KEBA I2C
    - Theobroma Systems Mule Multiplexer.

The Keba comes with a new driver, i2c-keba.c.
The Mule is an i2c multiplexer and it also comes with a new
driver, mux/i2c-mux-mule.c.

Core patch
----------
This pull request includes also a patch in the I2C framework, in
i2c-core-base.c where the runtime PM functions have been replaced
in order to allow to be accessed during the device add.

Devicetree
----------
Some cleanups in the devicetree, as well. nVidia and Qualcomm
bindings improve their "if:then:" blocks. While the aspeed
binding loses the "multi-master" property because it was
redundant.

The i2c-sprd binding has been converted to YAML.

Merge tag 'vfs-6.12.blocksize' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs

Pull vfs blocksize updates from Christian Brauner:
 "This contains the vfs infrastructure as well as the xfs bits to enable
  support for block sizes (bs) larger than page sizes (ps) plus a few
  fixes to related infrastructure.

  There has been efforts over the last 16 years to enable enable Large
  Block Sizes (LBS), that is block sizes in filesystems where bs > page
  size. Through these efforts we have learned that one of the main
  blockers to supporting bs > ps in filesystems has been a way to
  allocate pages that are at least the filesystem block size on the page
  cache where bs > ps.

  Thanks to various previous efforts it is possible to support bs > ps
  in XFS with only a few changes in XFS itself. Most changes are to the
  page cache to support minimum order folio support for the target block
  size on the filesystem.

  A motivation for Large Block Sizes today is to support high-capacity
  (large amount of Terabytes) QLC SSDs where the internal Indirection
  Unit (IU) are typically greater than 4k to help reduce DRAM and so in
  turn cost and space. In practice this then allows different
  architectures to use a base page size of 4k while still enabling
  support for block sizes aligned to the larger IUs by relying on high
  order folios on the page cache when needed.

  It also allows to take advantage of the drive's support for atomics
  larger than 4k with buffered IO support in Linux. As described this
  year at LSFMM, supporting large atomics greater than 4k enables
  databases to remove the need to rely on their own journaling, so they
  can disable double buffered writes, which is a feature different cloud
  providers are already enabling through custom storage solutions"

5f5e734432 kbuild: generate offset range data for builtin modules
Create file module.builtin.ranges that can be used to find where
built-in modules are located by their addresses. This will be useful for
tracing tools to find what functions are for various built-in modules.

The offset range data for builtin modules is generated using:
 - modules.builtin: associates object files with module names
 - vmlinux.map: provides load order of sections and offset of first member
    per section
 - vmlinux.o.map: provides offset of object file content per section
 - .*.cmd: build cmd file with KBUILD_MODFILE

The generated data will look like:

.text 00000000-00000000 = _text
.text 0000baf0-0000cb10 amd_uncore
.text 0009bd10-0009c8e0 iosf_mbi
...
.text 00b9f080-00ba011a intel_skl_int3472_discrete
.text 00ba0120-00ba03c0 intel_skl_int3472_discrete intel_skl_int3472_tps68470
.text 00ba03c0-00ba08d6 intel_skl_int3472_tps68470
...
.data 00000000-00000000 = _sdata
.data 0000f020-0000f680 amd_uncore

For each ELF section, it lists the offset of the first symbol.  This can
be used to determine the base address of the section at runtime.

Next, it lists (in strict ascending order) offset ranges in that section
that cover the symbols of one or more builtin modules.  Multiple ranges
can apply to a single module, and ranges can be shared between modules.

The CONFIG_BUILTIN_MODULE_RANGES option controls whether offset range data
is generated for kernel modules that are built into the kernel image.

How it works:

 1. The modules.builtin file is parsed to obtain a list of built-in
    module names and their associated object names (the .ko file that
    the module would be in if it were a loadable module, hereafter
    referred to as <kmodfile>).  This object name can be used to
    identify objects in the kernel compile because any C or assembler
    code that ends up into a built-in module will have the option
    -DKBUILD_MODFILE=<kmodfile> present in its build command, and those
    can be found in the .<obj>.cmd file in the kernel build tree.

    If an object is part of multiple modules, they will all be listed
    in the KBUILD_MODFILE option argument.

    This allows us to conclusively determine whether an object in the
    kernel build belong to any modules, and which.

 2. The vmlinux.map is parsed next to determine the base address of each
    top level section so that all addresses into the section can be
    turned into offsets.  This makes it possible to handle sections
    getting loaded at different addresses at system boot.

    We also determine an 'anchor' symbol at the beginning of each
    section to make it possible to calculate the true base address of
    a section at runtime (i.e. symbol address - symbol offset).

    We collect start addresses of sections that are included in the top
    level section.  This is used when vmlinux is linked using vmlinux.o,
    because in that case, we need to look at the vmlinux.o linker map to
    know what object a symbol is found in.

    And finally, we process each symbol that is listed in vmlinux.map
    (or vmlinux.o.map) based on the following structure:

    vmlinux linked from vmlinux.a:

      vmlinux.map:
        <top level section>
          <included section>  -- might be same as top level section)
            <object>          -- built-in association known
              <symbol>        -- belongs to module(s) object belongs to
              ...

    vmlinux linked from vmlinux.o:

      vmlinux.map:
        <top level section>
          <included section>  -- might be same as top level section)
            vmlinux.o         -- need to use vmlinux.o.map
              <symbol>        -- ignored
              ...

      vmlinux.o.map:
        <section>
            <object>          -- built-in association known
              <symbol>        -- belongs to module(s) object belongs to
              ...

 3. As sections, objects, and symbols are processed, offset ranges are
    constructed in a straight-forward way:

      - If the symbol belongs to one or more built-in modules:
          - If we were working on the same module(s), extend the range
            to include this object
          - If we were working on another module(s), close that range,
            and start the new one
      - If the symbol does not belong to any built-in modules:
          - If we were working on a module(s) range, close that range

Linus Torvalds
2004cef11e In the v6.12 scheduler development cycle we had 63 commits from 18 contributors:
- Implement the SCHED_DEADLINE server infrastructure - Daniel Bristot de Oliveira's
    last major contribution to the kernel:
 
      "SCHED_DEADLINE servers can help fixing starvation issues of low priority
      tasks (e.g., SCHED_OTHER) when higher priority tasks monopolize CPU
      cycles. Today we have RT Throttling; DEADLINE servers should be able to
      replace and improve that."
 
      (Daniel Bristot de Oliveira, Peter Zijlstra, Joel Fernandes,
       Youssef Esmat, Huang Shijie)
 
  - Preparatory changes for sched_ext integration:
 
      - Use set_next_task(.first) where required
      - Fix up set_next_task() implementations
      - Clean up DL server vs. core sched
      - Split up put_prev_task_balance()
      - Rework pick_next_task()
      - Combine the last put_prev_task() and the first set_next_task()
      - Rework dl_server
      - Add put_prev_task(.next)
 
       (Peter Zijlstra, with a fix by Tejun Heo)
 
  - Complete the EEVDF transition and refine EEVDF scheduling:
 
      - Implement delayed dequeue
      - Allow shorter slices to wakeup-preempt
      - Use sched_attr::sched_runtime to set request/slice suggestion
      - Document the new feature flags
      - Remove unused and duplicate-functionality fields
      - Simplify & unify pick_next_task_fair()
      - Misc debuggability enhancements
 
       (Peter Zijlstra, with fixes/cleanups by Dietmar Eggemann,
        Valentin Schneider and Chuyi Zhou)
 
  - Initialize the vruntime of a new task when it is first enqueued,
    resulting in significant decrease in latency of newly woken tasks.
    (Zhang Qiao)
 
  - Introduce SM_IDLE and an idle re-entry fast-path in __schedule()
    (K Prateek Nayak, Peter Zijlstra)
 
  - Clean up and clarify the usage of Clean up usage of rt_task()
    (Qais Yousef)
 
  - Preempt SCHED_IDLE entities in strict cgroup hierarchies
    (Tianchen Ding)
 
  - Clarify the documentation of time units for deadline scheduler
    parameters. (Christian Loehle)
 
  - Remove the HZ_BW chicken-bit feature flag introduced a year ago,
    the original change seems to be working fine.
    (Phil Auld)
 
  - Misc fixes and cleanups (Chen Yu, Dan Carpenter, Huang Shijie,
    Peilin He, Qais Yousefm and Vincent Guittot)

a1d1eb2f57 SCSI misc on 20240919
Updates to the usual drivers (ufs, smartpqi, NCR5380, mac_scsi, lpfc,
 mpi3mr).  There are no user visible core changes and a whole series of
 minor updates and fixes.  The largest core change is probably the
 simplification of the workqueue allocation path.

Merge tag 'random-6.12-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random

Pull random number generator updates from Jason Donenfeld:
 "Originally I'd planned on sending each of the vDSO getrandom()
  architecture ports to their respective arch trees. But as we started
  to work on this, we found lots of interesting issues in the shared
  code and infrastructure, the fixes for which the various archs needed
  to base their work.

  So in the end, this turned into a nice collaborative effort fixing up
  issues and porting to 5 new architectures -- arm64, powerpc64,
  powerpc32, s390x, and loongarch64 -- with everybody pitching in and
  commenting on each other's code. It was a fun development cycle.

  This contains:

   - Numerous fixups to the vDSO selftest infrastructure, getting it
     running successfully on more platforms, and fixing bugs in it.

   - Additions to the vDSO getrandom & chacha selftests. Basically every
     time manual review unearthed a bug in a revision of an arch patch,
     or an ambiguity, the tests were augmented.

     By the time the last arch was submitted for review, s390x, v1 of
     the series was essentially fine right out of the gate.

   - Fixes to the the generic C implementation of vDSO getrandom, to
     build and run successfully on all archs, decoupling it from
     assumptions we had (unintentionally) made on x86_64 that didn't
     carry through to the other architectures.

   - Port of vDSO getrandom to LoongArch64, from Xi Ruoyao and acked by
     Huacai Chen.

   - Port of vDSO getrandom to ARM64, from Adhemerval Zanella and acked
     by Will Deacon.

   - Port of vDSO getrandom to PowerPC, in both 32-bit and 64-bit
     varieties, from Christophe Leroy and acked by Michael Ellerman.

   - Port of vDSO getrandom to S390X from Heiko Carstens, the arch
     maintainer.

  While it'd be natural for there to be things to fix up over the course
  of the development cycle, these patches got a decent amount of review
  from a fairly diverse crew of folks on the mailing lists, and, for the
  most part, they've been cooking in linux-next, which has been helpful
  for ironing out build issues.

  In terms of architectures, I think that mostly takes care of the
  important 64-bit archs with hardware still being produced and running
  production loads in settings where vDSO getrandom is likely to help.

  Arguably there's still RISC-V left, and we'll see for 6.13 whether
  they find it useful and submit a port"

cc52dc2fe3 pwm: Changes for v6.12-rc1
This pull request contains some cleanups to the core and some mostly
 minor updates to a bunch of drivers and device tree bindings. One thing
 worth pointing out is that it contains an immutable branch containing
 support for a new mfd chip (Analog Devices ADP5585) with several sub
 drivers. So expect to get the four affected commits also from my fellow
 MFD and GPIO maintainers.
 
 Thanks go to Andrew Kreimer, Clark Wang, Conor Dooley, David Lechner,
 Dmitry Rokosov, Frank Li, Geert Uytterhoeven, George Stark, Jiapeng
 Chong, Krzysztof Kozlowski, Laurent Pinchart, Liao Chen, Liu Ying, Rob
 Herring and Wolfram Sang for code contributions and reviews and to Lee
 Jones for preparing the above mentioned immutable branch.

2471d2b3b2 * MTD changes
No particularly important patchset this cycle, but we have a few usual
 improvements: like using a better/more recent helper or checking a
 return value.
 
 * Raw NAND changes
 
 The use of for_each_child_of_node_scoped() has been spread into the
 subsystem drivers. Aside from that, a couple of exit path have been
 fixed (mtk, denali), the TI GPMC bindings have been enhanced to comply
 with up-to-date partition descriptions and as always there is a load of
 small and misc fixes.
 
 * SPI-NAND changes
 
 The most impacting series this cycle is bringing support for continuous
 reads in the SPI-NAND subsystem. This is a feature already merged in the
 raw NAND subsystem which allows optimizing the internal fetch times in
 the chip while reading sequential pages within an eraseblock. For now
 only Macronix NANDs benefit from this feature. While we are talking
 about Macronix, some of their chip need an explicit action for selecting
 a different plane, and support for it has also been brought.
 
 The bitflip threshold has also been set to the same arbitrary level as
 in the raw NAND subsystem to optimize wear leveling decisions, and
 finally support for a new Winbond chip has been added.
 
 * SPI NOR changes
 
 Notable changes:
 - Add Write Protect support for N25Q064A.
 - New flash support for Zetta ZD25Q128C and Spansion S28HS256T.
 - Fix a NULL dereference in probe path for flashes without a name. The
   probe path tries to access the name without checking its existence
   first. S28HS256T is the first flash to define its entry without a
   name, uncovering this issue.

067610ebaa RCU pull request for v6.12
This pull request contains the following branches:
 
 context_tracking.15.08.24a: Rename context tracking state related
         symbols and remove references to "dynticks" in various context
         tracking state variables and related helpers; force
         context_tracking_enabled_this_cpu() to be inlined to avoid
         leaving a noinstr section.
 
 csd.lock.15.08.24a: Enhance CSD-lock diagnostic reports; add an API
         to provide an indication of ongoing CSD-lock stall.
 
 nocb.09.09.24a: Update and simplify RCU nocb code to handle
         (de-)offloading of callbacks only for offline CPUs; fix RT
         throttling hrtimer being armed from offline CPU.
 
 rcutorture.14.08.24a: Remove redundant rcu_torture_ops get_gp_completed
         fields; add SRCU ->same_gp_state and ->get_comp_state
         functions; add generic test for NUM_ACTIVE_*RCU_POLL* for
         testing RCU and SRCU polled grace periods; add CFcommon.arch
         for arch-specific Kconfig options; print number of update types
         in rcu_torture_write_types();
         add rcutree.nohz_full_patience_delay testing to the TREE07
         scenario; add a stall_cpu_repeat module parameter to test
         repeated CPU stalls; add argument to limit number of CPUs a
         guest OS can use in torture.sh;
 
 rcustall.09.09.24a: Abbreviate RCU CPU stall warnings during CSD-lock
         stalls; Allow dump_cpu_task() to be called without disabling
         preemption; defer printing stall-warning backtrace when holding
         rcu_node lock.
 
 srcu.12.08.24a: Make SRCU gp seq wrap-around faster; add KCSAN checks
         for concurrent updates to ->srcu_n_exp_nodelay and
         ->reschedule_count which are used in heuristics governing
         auto-expediting of normal SRCU grace periods and
         grace-period-state-machine delays; mark idle SRCU-barrier
         callbacks to help identify stuck SRCU-barrier callback.
 
 rcu.tasks.14.08.24a: Remove RCU Tasks Rude asynchronous APIs as they
         are no longer used; stop testing RCU Tasks Rude asynchronous
         APIs; fix access to non-existent percpu regions; check
         processor-ID assumptions during chosen CPU calculation for
         callback enqueuing; update description of rtp->tasks_gp_seq
         grace-period sequence number; add rcu_barrier_cb_is_done()
         to identify whether a given rcu_barrier callback is stuck;
         mark idle Tasks-RCU-barrier callbacks; add
         *torture_stats_print() functions to print detailed
         diagnostics for Tasks-RCU variants; capture start time of
         rcu_barrier_tasks*() operation to help distinguish a hung
         barrier operation from a long series of barrier operations.
 
 rcu_scaling_tests.15.08.24a:
         refscale: Add a TINY scenario to support tests of Tiny RCU
         and Tiny SRCU; Optimize process_durations() operation;
 
         rcuscale: Dump stacks of stalled rcu_scale_writer() instances;

         async module parameter is specified for RCU implementations
         that do not have async primitives such as RCU Tasks Rude;
         make all writer tasks report upon hang; tolerate repeated

3f8df62852 Merge tag 'kvm-x86-vmx-6.12' of https://github.com/kvm-x86/linux into HEAD
KVM VMX changes for 6.12:

 - Set FINAL/PAGE in the page fault error code for EPT Violations if and only
   if the GVA is valid.  If the GVA is NOT valid, there is no guest-side page
   table walk and so stuffing paging related metadata is nonsensical.

 - Fix a bug where KVM would incorrectly synthesize a nested VM-Exit instead of
   emulating posted interrupt delivery to L2.

 - Add a lockdep assertion to detect unsafe accesses of vmcs12 structures.

 - Harden eVMCS loading against an impossible NULL pointer deref (really truly
   should be impossible).

 - Minor SGX fix and a cleanup.

c09dd2bb57 Merge branch 'kvm-redo-enable-virt' into HEAD
Register KVM's cpuhp and syscore callbacks when enabling virtualization in
hardware, as the sole purpose of said callbacks is to disable and re-enable
virtualization as needed.

The primary motivation for this series is to simplify dealing with enabling
virtualization for Intel's TDX, which needs to enable virtualization
when kvm-intel.ko is loaded, i.e. long before the first VM is created.

That said, this is a nice cleanup on its own.  By registering the callbacks
on-demand, the callbacks themselves don't need to check kvm_usage_count,
because their very existence implies a non-zero count.

Patch 1 (re)adds a dedicated lock for kvm_usage_count.  This avoids a
lock ordering issue between cpus_read_lock() and kvm_lock.  The lock
ordering issue still exist in very rare cases, and will be fixed for
good by switching vm_list to an (S)RCU-protected list.

55f50b2f86 Merge branch 'kvm-memslot-zap-quirk' into HEAD
Today whenever a memslot is moved or deleted, KVM invalidates the entire
page tables and generates fresh ones based on the new memslot layout.

This behavior traditionally was kept because of a bug which was never
fully investigated and caused VM instability with assigned GeForce
GPUs.  It generally does not have a huge overhead, because the old
MMU is able to reuse cached page tables and the new one is more
scalabale and can resolve EPT violations/nested page faults in parallel,
but it has worse performance if the guest frequently deletes and
adds small memslots, and it's entirely not viable for TDX.  This is
because TDX requires re-accepting of private pages after page dropping.

For non-TDX VMs, this series therefore introduces the
KVM_X86_QUIRK_SLOT_ZAP_ALL quirk, enabling users to control the behavior
of memslot zapping when a memslot is moved/deleted.  The quirk is turned
on by default, leading to the zapping of all SPTEs when a memslot is
moved/deleted; users however have the option to turn off the quirk,
which limits the zapping only to those SPTEs hat lie within the range
of memslot being moved/deleted.

2f27fce671 sound updates for 6.12-rc1
A fairly big update at this time, both in core and driver sides.
 
 The core received rewrites in PCM buffer allocation handling and
 locking optimizations, PCM rate updates followed by lots of cleanups.
 
 In ASoC side, the legacy Intel drivers have been deprecated by AVS
 drivers which leaded to the significant amount of code reduction.
 SoundWire driver updates and other cleanups contributed more code
 reduction, too.
 
 USB-audio driver received a large cleanup of its big quirk table, and
 the old snd_print*() API usages in many legacy drivers are replaced
 with the standard print API.
 
 Here are some highlights:
 
 Core:
 - More optimized locking in ALSA control code
 - Rewrites of memalloc helpers for better DMA API usage
 - Drop of obsoleted vmalloc PCM buffer helper API
 - Continued MIDI2 UMP updates
 - Support of a new user-space driven timer instance
 - Update for more PCM support rates and cleanups
 - Xrun counter report in the proc files
 
 ASoC:
 - Continued simplification and cleanup works for ASoC
 - Extensive cleanups and refactoring of the Soundwire drivers
 - Removal of Intel machine support obsoleted by the AVS driver
 - Lots of DT schema conversions
 - Machine support for many AMD and Intel x86 platforms
 - Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek RTL1320
   SoundWire and rev C, and Texas Instruments TAS2563
 
 USB-audio:
 - Add support of multiple control interfaces
 - A large rewrite of quirk table with macros
 - Support for RME Digiface USB
 
 HD-audio:
 - Cleanup of quirk code for Samsung Galaxy laptops
 - Clean up of detection of Cirrus codecs
 - C-Media CM9825 HD-audio codec support

b8979c6b4d soc: driver updates for 6.12
The driver updates seem larger this time around, with changes
 is many of the SoC specific drivers, both the custom drivers/soc
 ones and the closely related subsystems (memory, bus, firmware,
 reset, ...).
 
 The at91 platform gains support for sam9x7 chips in the soc and
 power management code. This is the latest variant of one of the
 oldest still supported SoC families, using the ARM9 (ARMv5) core.
 
 As usual, the qualcomm snapdragon platform gets a ton of updates in many
 of their drivers to add more features and additional SoC support. Most
 of these are somewhat firmware related as the platform has a number of
 firmware based interfaces to the kernel. A notable addition here is the
 inclusion of trace events to two of these drivers.
 
 Herve Codina and Christophe Leroy are now sending updates for
 drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC
 and Arm specific platforms and has previously been problematic to
 maintain. The first update here contains support for newer PowerPC
 variants and some cleanups.
 
 The turris mox firmware driver has a number of updates, mostly cleanups.
 
 The Arm SCMI firmware driver gets a major rework to modularize
 the existing code into separately loadable drivers for the various
 transports, the addition of custom NXP i.MX9 interfaces and a
 number of smaller updates.
 
 The Arm FF-A firmware driver gets a feature update to support
 the v1.2 version of the specification.
 
 The reset controller drivers have some smaller cleanups and a newly
 added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs.
 
 The memory controller drivers get some cleanups and refactoring
 for Tegra, TI, Freescale/NXP and a couple more platforms.
 
 Finally there are lots of minor updates to firmware (raspberry pi,
 tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra, amlogic,
 mediatek) drivers and their DT bindings.

7b17f5ebd5 soc: devicetree updates for 6.12
New SoC support for Broadcom bcm2712 (Raspberry Pi 5) and Renesas
 R9A09G057 (RZ/V2H(P)) and Qualcomm Snapdragon 414 (MSM8929), all three
 of these are variants of already supported chips, in particular the last
 one is almost identical to MSM8939.
 
 Lots of updates to Mediatek, ASpeed, Rockchips, Amlogic, Qualcomm,
 STM32, NXP i.MX, Sophgo, TI K3, Renesas, Microchip at91, NVIDIA Tegra,
 and T-HEAD.
 
 The added Qualcomm platform support once again dominates the changes,
 with seven phones and three laptops getting added in addition to
 many new features on existing machines. The Snapdragon X1E support
 specifically keeps improving.
 
 The other new machines are:
 
  - eight new machines using various 64-bit Rockchips SoCs, both
    on the consumer/gaming side and developer boards
  - three industrial boards with 64-bit i.MX, which is a very
    low number for them.
  - four more servers using a 32-bit Speed BMC
  - three boards using STM32MP1 SoCs
  - one new machine each using allwinner, amlogic, broadcom
    and renesas chips.

9ea925c806 Updates for timers and timekeeping:
- Core:
 
 	- Overhaul of posix-timers in preparation of removing the
 	  workaround for periodic timers which have signal delivery
 	  ignored.
 
         - Remove the historical extra jiffie in msleep()
 
 	  msleep() adds an extra jiffie to the timeout value to ensure
 	  minimal sleep time. The timer wheel ensures minimal sleep
 	  time since the large rewrite to a non-cascading wheel, but the
 	  extra jiffie in msleep() remained unnoticed. Remove it.
 
         - Make the timer slack handling correct for realtime tasks.
 
 	  The procfs interface is inconsistent and does neither reflect
 	  reality nor conforms to the man page. Show the correct 0 slack
 	  for real time tasks and enforce it at the core level instead of
 	  having inconsistent individual checks in various timer setup
 	  functions.
 
         - The usual set of updates and enhancements all over the place.
 
   - Drivers:
 
         - Allow the ACPI PM timer to be turned off during suspend
 
 	- No new drivers
 
 	- The usual updates and enhancements in various drivers

Pull timer updates from Thomas Gleixner:
 "Core:

   - Overhaul of posix-timers in preparation of removing the workaround
     for periodic timers which have signal delivery ignored.

   - Remove the historical extra jiffie in msleep()

     msleep() adds an extra jiffie to the timeout value to ensure
     minimal sleep time. The timer wheel ensures minimal sleep time
     since the large rewrite to a non-cascading wheel, but the extra
     jiffie in msleep() remained unnoticed. Remove it.

   - Make the timer slack handling correct for realtime tasks.

     The procfs interface is inconsistent and does neither reflect
     reality nor conforms to the man page. Show the correct 0 slack for
     real time tasks and enforce it at the core level instead of having
     inconsistent individual checks in various timer setup functions.

   - The usual set of updates and enhancements all over the place.

  Drivers:

   - Allow the ACPI PM timer to be turned off during suspend

   - No new drivers

   - The usual updates and enhancements in various drivers"

Merge tag 'lsm-pr-20240911' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm

Pull lsm updates from Paul Moore:

 - Move the LSM framework to static calls

   This transitions the vast majority of the LSM callbacks into static
   calls. Those callbacks which haven't been converted were left as-is
   due to the general ugliness of the changes required to support the
   static call conversion; we can revisit those callbacks at a future
   date.

 - Add the Integrity Policy Enforcement (IPE) LSM

   This adds a new LSM, Integrity Policy Enforcement (IPE). There is
   plenty of documentation about IPE in this patches, so I'll refrain
   from going into too much detail here, but the basic motivation behind
   IPE is to provide a mechanism such that administrators can restrict
   execution to only those binaries which come from integrity protected
   storage, e.g. a dm-verity protected filesystem. You will notice that
   IPE requires additional LSM hooks in the initramfs, dm-verity, and
   fs-verity code, with the associated patches carrying ACK/review tags
   from the associated maintainers. We couldn't find an obvious
   maintainer for the initramfs code, but the IPE patchset has been
   widely posted over several years.

   Both Deven Bowers and Fan Wu have contributed to IPE's development
   over the past several years, with Fan Wu agreeing to serve as the IPE
   maintainer moving forward. Once IPE is accepted into your tree, I'll
   start working with Fan to ensure he has the necessary accounts, keys,
   etc. so that he can start submitting IPE pull requests to you
   directly during the next merge window.

 - Move the lifecycle management of the LSM blobs to the LSM framework

   Management of the LSM blobs (the LSM state buffers attached to
   various kernel structs, typically via a void pointer named "security"
   or similar) has been mixed, some blobs were allocated/managed by
   individual LSMs, others were managed by the LSM framework itself.

   Starting with this pull we move management of all the LSM blobs,
   minus the XFRM blob, into the framework itself, improving consistency
   across LSMs, and reducing the amount of duplicated code across LSMs.
   Due to some additional work required to migrate the XFRM blob, it has
   been left as a todo item for a later date; from a practical
   standpoint this omission should have little impact as only SELinux
   provides a XFRM LSM implementation.

 - Fix problems with the LSM's handling of F_SETOWN

   The LSM hook for the fcntl(F_SETOWN) operation had a couple of
   problems: it was racy with itself, and it was disconnected from the
   associated DAC related logic in such a way that the LSM state could
   be updated in cases where the DAC state would not. We fix both of
   these problems by moving the security_file_set_fowner() hook into the
   same section of code where the DAC attributes are updated. Not only
   does this resolve the DAC/LSM synchronization issue, but as that code
   block is protected by a lock, it also resolve the race condition.

 - Fix potential problems with the security_inode_free() LSM hook

   Due to use of RCU to protect inodes and the placement of the LSM hook
   associated with freeing the inode, there is a bit of a challenge when
   it comes to managing any LSM state associated with an inode. The VFS
   folks are not open to relocating the LSM hook so we have to get
   creative when it comes to releasing an inode's LSM state.
   Traditionally we have used a single LSM callback within the hook that
   is triggered when the inode is "marked for death", but not actually
   released due to RCU.

   Unfortunately, this causes problems for LSMs which want to take an
   action when the inode's associated LSM state is actually released; so
   we add an additional LSM callback, inode_free_security_rcu(), that is
   called when the inode's LSM state is released in the RCU free
   callback.

 - Refactor two LSM hooks to better fit the LSM return value patterns

   The vast majority of the LSM hooks follow the "return 0 on success,
   negative values on failure" pattern, however, there are a small
   handful that have unique return value behaviors which has caused
   confusion in the past and makes it difficult for the BPF verifier to
   properly vet BPF LSM programs. This includes patches to
   convert two of these"special" LSM hooks to the common 0/-ERRNO pattern.

 - Various cleanups and improvements

   A handful of patches to remove redundant code, better leverage the
   IS_ERR_OR_NULL() helper, add missing "static" markings, and do some
   minor style fixups.

Merge tag 'vfs-6.12.netfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull netfs updates from Christian Brauner:
 "This contains the work to improve read/write performance for the new
  netfs library.

  The main performance enhancing changes are:

   - Define a structure, struct folio_queue, and a new iterator type,
     ITER_FOLIOQ, to hold a buffer as a replacement for ITER_XARRAY. See
     that patch for questions about naming and form.

     ITER_FOLIOQ is provided as a replacement for ITER_XARRAY. The
     problem with an xarray is that accessing it requires the use of a
     lock (typically the RCU read lock) - and this means that we can't
     supply iterate_and_advance() with a step function that might sleep
     (crypto for example) without having to drop the lock between pages.
     ITER_FOLIOQ is the iterator for a chain of folio_queue structs,
     where each folio_queue holds a small list of folios. A folio_queue
     struct is a simpler structure than xarray and is not subject to
     concurrent manipulation by the VM. folio_queue is used rather than
     a bvec[] as it can form lists of indefinite size, adding to one end
     and removing from the other on the fly.

   - Provide a copy_folio_from_iter() wrapper.

   - Make cifs RDMA support ITER_FOLIOQ.

   - Use folio queues in the write-side helpers instead of xarrays.

   - Add a function to reset the iterator in a subrequest.

   - Simplify the write-side helpers to use sheaves to skip gaps rather
     than trying to work out where gaps are.

   - In afs, make the read subrequests asynchronous, putting them into
     work items to allow the next patch to do progressive
     unlocking/reading.

   - Overhaul the read-side helpers to improve performance.

   - Fix the caching of a partial block at the end of a file.

   - Allow a store to be cancelled.

  Then some changes for cifs to make it use folio queues instead of
  xarrays for crypto bufferage:

   - Use raw iteration functions rather than manually coding iteration
     when hashing data.

   - Switch to using folio_queue for crypto buffers.

   - Remove the xarray bits.

  Make some adjustments to the /proc/fs/netfs/stats file such that:

   - All the netfs stats lines begin 'Netfs:' but change this to
     something a bit more useful.

   - Add a couple of stats counters to track the numbers of skips and
     waits on the per-inode writeback serialisation lock to make it
     easier to check for this as a source of performance loss.

  Miscellaneous work:

   - Ensure that the sb_writers lock is taken around
     vfs_{set,remove}xattr() in the cachefiles code.

   - Reduce the number of conditional branches in netfs_perform_write().

   - Move the CIFS_INO_MODIFIED_ATTR flag to the netfs_inode struct and
     remove cifs_post_modify().

   - Move the max_len/max_nr_segs members from netfs_io_subrequest to
     netfs_io_request as they're only needed for one subreq at a time.

   - Add an 'unknown' source value for tracing purposes.

   - Remove NETFS_COPY_TO_CACHE as it's no longer used.

   - Set the request work function up front at allocation time.

   - Use bh-disabling spinlocks for rreq->lock as cachefiles completion

Pull procfs updates from Christian Brauner:
 "This contains the following changes for procfs:

   - Add config options and parameters to block forcing memory writes.

     This adds a Kconfig option and boot param to allow removing the
     FOLL_FORCE flag from /proc/<pid>/mem write calls as this can be
     used in various attacks.

     The traditional forcing behavior is kept as default because it can
     break GDB and some other use cases.

     This is the simpler version that you had requested.

   - Restrict overmounting of ephemeral entities.

     It is currently possible to mount on top of various ephemeral
     entities in procfs. This specifically includes magic links. To
     recap, magic links are links of the form /proc/<pid>/fd/<nr>. They
     serve as references to a target file and during path lookup they
     cause a jump to the target path. Such magic links disappear if the
     corresponding file descriptor is closed.

     Currently it is possible to overmount such magic links. This is
     mostly interesting for an attacker that wants to somehow trick a
     process into e.g., reopening something that it didn't intend to
     reopen or to hide a malicious file descriptor.

     But also it risks leaking mounts for long-running processes. When
     overmounting a magic link like above, the mount will not be
     detached when the file descriptor is closed. Only the target
     mountpoint will disappear. Which has the consequence of making it
     impossible to unmount that mount afterwards. So the mount will
     stick around until the process exits and the /proc/<pid>/ directory
     is cleaned up during proc_flush_pid() when the dentries are pruned
     and invalidated.

     That in turn means it's possible for a program to accidentally leak
     mounts and it's also possible to make a task leak mounts without
     it's knowledge if the attacker just keeps overmounting things under
     /proc/<pid>/fd/<nr>.

     Disallow overmounting of such ephemeral entities.

   - Cleanup the readdir method naming in some procfs file operations.

Merge tag 'vfs-6.12.misc' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs

Pull misc vfs updates from Christian Brauner:
 "This contains the usual pile of misc updates:

  Features:

   - Add F_CREATED_QUERY fcntl() that allows userspace to query whether
     a file was actually created. Often userspace wants to know whether
     an O_CREATE request did actually create a file without using
     O_EXCL. The current logic is that to first attempts to open the
     file without O_CREAT | O_EXCL and if ENOENT is returned userspace
     tries again with both flags. If that succeeds all is well. If it
     now reports EEXIST it retries.

     That works fairly well but some corner cases make this more
     involved. If this operates on a dangling symlink the first openat()
     without O_CREAT | O_EXCL will return ENOENT but the second openat()
     with O_CREAT | O_EXCL will fail with EEXIST.

     The reason is that openat() without O_CREAT | O_EXCL follows the
     symlink while O_CREAT | O_EXCL doesn't for security reasons. So
     it's not something we can really change unless we add an explicit
     opt-in via O_FOLLOW which seems really ugly.

     All available workarounds are really nasty (fanotify, bpf lsm etc)
     so add a simple fcntl().

   - Try an opportunistic lookup for O_CREAT. Today, when opening a file
     we'll typically do a fast lookup, but if O_CREAT is set, the kernel
     always takes the exclusive inode lock. This was likely done with
     the expectation that O_CREAT means that we always expect to do the
     create, but that's often not the case. Many programs set O_CREAT
     even in scenarios where the file already exists (see related
     F_CREATED_QUERY patch motivation above).

     The series contained in the pr rearranges the pathwalk-for-open
     code to also attempt a fast_lookup in certain O_CREAT cases. If a
     positive dentry is found, the inode_lock can be avoided altogether
     and it can stay in rcuwalk mode for the last step_into.

   - Expose the 64 bit mount id via name_to_handle_at()

     Now that we provide a unique 64-bit mount ID interface in statx(2),
     we can now provide a race-free way for name_to_handle_at(2) to
     provide a file handle and corresponding mount without needing to
     worry about racing with /proc/mountinfo parsing or having to open a
     file just to do statx(2).

     While this is not necessary if you are using AT_EMPTY_PATH and
     don't care about an extra statx(2) call, users that pass full paths
     into name_to_handle_at(2) need to know which mount the file handle
     comes from (to make sure they don't try to open_by_handle_at a file
     handle from a different filesystem) and switching to AT_EMPTY_PATH
     would require allocating a file for every name_to_handle_at(2) call

   - Add a per dentry expire timeout to autofs

     There are two fairly well known automounter map formats, the autofs
     format and the amd format (more or less System V and Berkley).

     Some time ago Linux autofs added an amd map format parser that
     implemented a fair amount of the amd functionality. This was done
     within the autofs infrastructure and some functionality wasn't
     implemented because it either didn't make sense or required extra
     kernel changes. The idea was to restrict changes to be within the
     existing autofs functionality as much as possible and leave changes
     with a wider scope to be considered later.

     One of these changes is implementing the amd options:
      1) "unmount", expire this mount according to a timeout (same as
         the current autofs default).
      2) "nounmount", don't expire this mount (same as setting the
         autofs timeout to 0 except only for this specific mount) .
      3) "utimeout=<seconds>", expire this mount using the specified
         timeout (again same as setting the autofs timeout but only for
         this mount)

     To implement these options per-dentry expire timeouts need to be
     implemented for autofs indirect mounts. This is because all map
     keys (mounts) for autofs indirect mounts use an expire timeout
     stored in the autofs mount super block info. structure and all
     indirect mounts use the same expire timeout.

  Fixes:

   - Fix missing fput for FSCONFIG_SET_FD in autofs

   - Use param->file for FSCONFIG_SET_FD in coda

   - Delete the 'fs/netfs' proc subtreee when netfs module exits

   - Make sure that struct uid_gid_map fits into a single cacheline

   - Don't flush in-flight wb switches for superblocks without cgroup
     writeback

   - Correcting the idmapping mount example in the idmapping
     documentation

   - Fix a race between evice_inodes() and find_inode() and iput()

   - Refine the show_inode_state() macro definition in writeback code

   - Prevent dump_mapping() from accessing invalid dentry.d_name.name

   - Show actual source for debugfs in /proc/mounts

   - Annotate data-race of busy_poll_usecs in eventpoll

   - Don't WARN for racy path_noexec check in exec code

   - Handle OOM on mnt_warn_timestamp_expiry()

   - Fix some spelling in the iomap design documentation

   - Fix typo in procfs comment

   - Fix typo in fs/namespace.c comment

  Cleanups:

   - Add the VFS git tree to the MAINTAINERS file

   - Move FMODE_UNSIGNED_OFFSET to fop_flags freeing up another f_mode
     bit in struct file bringing us to 5 free f_mode bits

   - Remove the __I_DIO_WAKEUP bit from i_state flags as we can simplify
     the wait mechanism

   - Remove the unused path_put_init() helper

   - Replace a __u32 with u32 for s_fsnotify_mask as __u32 is uapi
     specific

   - Replace the unsigned long i_state member with a u32 i_state member
     in struct inode freeing up 4 bytes in struct inode. Instead of
     using the bit based wait apis we're now using the var event apis
     and using the individual bytes of the i_state member to wait on
     state changes

   - Explain how per-syscall AT_* flags should be allocated

   - Use in_group_or_capable() helper to simplify the posix acl mode
     update code

   - Switch to LIST_HEAD() in fsync_buffers_list() to simplify the code

   - Removed comment about d_rcu_to_refcount() as that function doesn't
     exist anymore

   - Add kernel documentation for lookup_fast()

   - Don't re-zero evenpoll fields

   - Remove outdated comment after close_fd()

   - Fix imprecise wording in comment about the pipe filesystem

   - Drop GFP_NOFAIL mode from alloc_page_buffers

   - Missing blank line warnings and struct declaration improved in
     file_table

   - Annotate struct poll_list with __counted_by()

   - Remove the unused read parameter in percpu-rwsem

   - Remove linux/prefetch.h include from direct-io code

   - Use kmemdup_array instead of kmemdup for multiple allocation in
     mnt_idmapping code

   - Remove unused mnt_cursor_del() declaration

  Performance tweaks:

   - Dodge smp_mb in break_lease and break_deleg in the common case

   - Only read fops once in fops_{get,put}()

   - Use RCU in ilookup()

   - Elide smp_mb in iversion handling in the common case

Pull thermal control updates from Rafael Wysocki:
 "These mostly continue to rework the thermal core and the thermal zone
  driver interface to make the code more straightforward and reduce
  bloat

  The most significant piece of this work is a change of the code
  related to binding cooling devices to thermal zones which, among other
  things, replaces two previously existing thermal zone operations with
  one allowing driver implementations to be much simpler

  There is also a new thermal core testing module allowing mock thermal
  zones to be created and controlled via debugfs in order to exercise
  the thermal core functionality. It is expected to be used for
  implementing thermal core self tests in the future

Pull power management updates from Rafael Wysocki:
 "By the number of new lines of code, the most visible change here is
  the addition of hybrid CPU capacity scaling support to the
  intel_pstate driver. Next are the amd-pstate driver changes related to
  the calculation of the AMD boost numerator and preferred core
  detection.

  As far as new hardware support is concerned, the intel_idle driver
  will now handle Granite Rapids Xeon processors natively, the
  intel_rapl power capping driver will recognize family 1Ah of AMD
  processors and Intel ArrowLake-U chipos, and intel_pstate will handle
  Granite Rapids and Sierra Forest chips in the out-of-band (OOB) mode.

  Apart from the above, there is a usual collection of assorted fixes
  and code cleanups in many places and there are tooling updates.

  Specifics:

   - Remove LATENCY_MULTIPLIER from cpufreq (Qais Yousef)

   - Add support for Granite Rapids and Sierra Forest in OOB mode to the
     intel_pstate cpufreq driver (Srinivas Pandruvada)

   - Add basic support for CPU capacity scaling on x86 and make the
     intel_pstate driver set asymmetric CPU capacity on hybrid systems
     without SMT (Rafael Wysocki)

   - Add missing MODULE_DESCRIPTION() macros to the powerpc cpufreq
     driver (Jeff Johnson)

Merge patch series "Svvptc extension to remove preventive sfence.vma"
Alexandre Ghiti <alexghiti@rivosinc.com> says:

In RISC-V, after a new mapping is established, a sfence.vma needs to be
emitted for different reasons:

- if the uarch caches invalid entries, we need to invalidate it otherwise
  we would trap on this invalid entry,
- if the uarch does not cache invalid entries, a reordered access could fail
  to see the new mapping and then trap (sfence.vma acts as a fence).

We can actually avoid emitting those (mostly) useless and costly sfence.vma
by handling the traps instead:

- for new kernel mappings: only vmalloc mappings need to be taken care of,
  other new mapping are rare and already emit the required sfence.vma if
  needed.
  That must be achieved very early in the exception path as explained in
  patch 3, and this also fixes our fragile way of dealing with vmalloc faults.

- for new user mappings: Svvptc makes update_mmu_cache() a no-op but we can
  take some gratuitous page faults (which are very unlikely though).

Patch 1 and 2 introduce Svvptc extension probing.

On our uarch that does not cache invalid entries and a 6.5 kernel, the
gains are measurable:

* Kernel boot:                  6%
* ltp - mmapstress01:           8%
* lmbench - lat_pagefault:      20%
* lmbench - lat_mmap:           5%

Here are the corresponding numbers of sfence.vma emitted:

* Ubuntu boot to login:
