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.

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:
interrupt-map: [[0, 0, 1, 0, 0, 4, 1, 0], [1, 0, 1, 4, 2, 0, 1, 0], ...
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.

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.

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.

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:

make CHECK_DTBS=y rockchip/rv1108-elgin-r1.dtb -j12

  DTC [C] arch/arm/boot/dts/rockchip/rv1108-elgin-r1.dtb
rv1108-elgin-r1.dtb:display@0: 'spi-cpha', 'spi-cpol' do not match any of the regexes:
...

Fix this problem by introducing a specific binding for the Elgin
JG10309-01 SPI-controlled display.

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.

3efc57369a x86: 
* 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

   - 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

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
 the serial apis, and lots of other driver updates and fixes.
 
 Included in here are:

   - 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

aa758763be docs: tproxy: ignore non-transparent sockets in iptables 
The iptables example was added in commit d2f26037a3 (netfilter: Add
documentation for tproxy, 2008-10-08), but xt_socket 'transparent'
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.
