5302a5c8be xfs: only clear log incompat flags at clean unmount 
While reviewing the online fsck patchset, someone spied the
xfs_swapext_can_use_without_log_assistance function and wondered why we
go through this inverted-bitmask dance to avoid setting the
XFS_SB_FEAT_INCOMPAT_LOG_SWAPEXT feature.

(The same principles apply to the logged extended attribute update
feature bit in the since-merged LARP series.)

The reason for this dance is that xfs_add_incompat_log_feature is an
expensive operation -- it forces the log, pushes the AIL, and then if
nobody's beaten us to it, sets the feature bit and issues a synchronous
write of the primary superblock.  That could be a one-time cost
amortized over the life of the filesystem, but the log quiesce and cover
operations call xfs_clear_incompat_log_features to remove feature bits
opportunistically.  On a moderately loaded filesystem this leads to us
cycling those bits on and off over and over, which hurts performance.

Why do we clear the log incompat bits?  Back in ~2020 I think Dave and I
had a conversation on IRC[2] about what the log incompat bits represent.
IIRC in that conversation we decided that the log incompat bits protect
unrecovered log items so that old kernels won't try to recover them and
barf.  Since a clean log has no protected log items, we could clear the
bits at cover/quiesce time.

As Dave Chinner pointed out in the thread, clearing log incompat bits at
unmount time has positive effects for golden root disk image generator
setups, since the generator could be running a newer kernel than what
gets written to the golden image -- if there are log incompat fields set
in the golden image that was generated by a newer kernel/OS image
builder then the provisioning host cannot mount the filesystem even
though the log is clean and recovery is unnecessary to mount the
filesystem.

Given that it's expensive to set log incompat bits, we really only want
to do that once per bit per mount.  Therefore, I propose that we only
clear log incompat bits as part of writing a clean unmount record.  Do
this by adding an operational state flag to the xfs mount that guards
whether or not the feature bit clearing can actually take place.

This eliminates the l_incompat_users rwsem that we use to protect a log
cleaning operation from clearing a feature bit that a frontend thread is
trying to set -- this lock adds another way to fail w.r.t. locking.  For
the swapext series, I shard that into multiple locks just to work around
the lockdep complaints, and that's fugly.

27fd80851d Misc x86 fixes: 
- Follow up fixes for the BHI mitigations code.
 
  - Fix !SPECULATION_MITIGATIONS bug not turning off
    mitigations as expected.
 
  - Work around an APIC emulation bug when the kernel is built with
    Clang and run as a SEV guest.
 
  - Follow up x86 topology fixes.
 
 Note that there's minor cleanups included in the BHI fixes,
 which we'd normally delay to the next merge window, but the
 BHI mitigations code is new and will be backported widely,
 so we thought it would be better to have a unified codebase
 at this stage. (Let me know if that assumption is wrong and
 I'll rebase it.)

399f4dae68 virtio: bugfixes 
Some small, obvious (in hindsight) bugfixes:
 
 - new ioctl in vhost-vdpa has a wrong # - not too late to fix
 
 - vhost has apparently been lacking an smp_rmb() -
   due to code duplication :( The duplication will be fixed in
   the next merge cycle, this is a minimal fix.
 
 - an error message in vhost talks about guest moving used index -
   which of course never happens, guest only ever moves the
   available index.
 
 - i2c-virtio didn't set the driver owner so it did not get
   refcounted correctly.

Notable user impacting bugs
 
 - On multi device filesystems, recovery was looping in
   btree_trans_too_many_iters(). This checks if a transaction has touched
   too many btree paths (because of iteration over many keys), and isuses
   a restart to drop unneeded paths. But it's now possible for some paths
   to exceed the previous limit without iteration in the interior btree
   update path, since the transaction commit will do alloc updates for
   every old and new btree node, and during journal replay we don't use
   the btree write buffer for locking reasons and thus those updates use
   btree paths when they wouldn't normally.
 
 - Fix a corner case in rebalance when moving extents on a durability=0
   device. This wouldn't be hit when a device was formatted with
   durability=0 since in that case we'll only use it as a write through
   cache (only cached extents will live on it), but durability can now be
   changed on an existing device.
 
 - bch2_get_acl() could rarely forget to handle a transaction restart;
   this manifested as the occasional missing acl that came back after
   dropping caches.
 
 - Fix a major performance regression on high iops multithreaded write
   workloads (only since 6.9-rc1); a previous fix for a deadlock in the

5f882f3b0a x86/bugs: Clarify that syscall hardening isn't a BHI mitigation 
While syscall hardening helps prevent some BHI attacks, there's still
other low-hanging fruit remaining.  Don't classify it as a mitigation
and make it clear that the system may still be vulnerable if it doesn't
have a HW or SW mitigation enabled.

2bb69f5fc7 x86 mitigations for the native BHI hardware vulnerabilty: 
Branch History Injection (BHI) attacks may allow a malicious application to
 influence indirect branch prediction in kernel by poisoning the branch
 history. eIBRS isolates indirect branch targets in ring0.  The BHB can
 still influence the choice of indirect branch predictor entry, and although
 branch predictor entries are isolated between modes when eIBRS is enabled,
 the BHB itself is not isolated between modes.
 
 Add mitigations against it either with the help of microcode or with
 software sequences for the affected CPUs.

 "Mitigations for the native BHI hardware vulnerabilty:

  Branch History Injection (BHI) attacks may allow a malicious
  application to influence indirect branch prediction in kernel by
  poisoning the branch history. eIBRS isolates indirect branch targets

[ This also ends up enabling the full mitigation by default despite the
  system call hardening, because apparently there are other indirect
  calls that are still sufficiently reachable, and the 'auto' case just
  isn't hardened enough.

  We'll have some more inevitable tweaking in the future    - Linus ]

95a6ccbdc7 x86/bhi: Mitigate KVM by default 
BHI mitigation mode spectre_bhi=auto does not deploy the software
mitigation by default. In a cloud environment, it is a likely scenario
where userspace is trusted but the guests are not trusted. Deploying
system wide mitigation in such cases is not desirable.

Update the auto mode to unconditionally mitigate against malicious
guests. Deploy the software sequence at VMexit in auto mode also, when
hardware mitigation is not available. Unlike the force =on mode,
software sequence is not deployed at syscalls in auto mode.

ec9404e40e x86/bhi: Add BHI mitigation knob 
Branch history clearing software sequences and hardware control
BHI_DIS_S were defined to mitigate Branch History Injection (BHI).

Add cmdline spectre_bhi={on|off|auto} to control BHI mitigation:

 auto - Deploy the hardware mitigation BHI_DIS_S, if available.
 on   - Deploy the hardware mitigation BHI_DIS_S, if available,
        otherwise deploy the software sequence at syscall entry and
	VMexit.
 off  - Turn off BHI mitigation.

The default is auto mode which does not deploy the software sequence
mitigation.  This is because of the hardening done in the syscall
dispatch path, which is the likely target of BHI.

ffe6176b7f virtio: store owner from modules with register_virtio_driver() 
Modules registering driver with register_virtio_driver() might forget to
set .owner field.  i2c-virtio.c for example has it missing.  The field
is used by some other kernel parts for reference counting
(try_module_get()), so it is expected that drivers will set it.

Solve the problem by moving this task away from the drivers to the core
virtio code, just like we did for platform_driver in
commit 9447057eaf ("platform_device: use a macro instead of
platform_driver_register").

commit 691632f0e8 ("Merge tag 's390-6.9-1' of

built with LLVM=1 when using LLVM 18.1.0, which is the first version
that has SystemZ support implemented in ld.lld and llvm-objcopy.

Update the supported architectures table in the Kbuild LLVM
documentation to note this explicitly to make it more discoverable by
users and other developers. Additionally, this brings s390 in line with
the rest of the architectures in the table, which all support LLVM=1.

7003de8a22 dt-bindings: bluetooth: add 'qcom,local-bd-address-broken' 
Several Qualcomm Bluetooth controllers lack persistent storage for the
device address and instead one can be provided by the boot firmware
using the 'local-bd-address' devicetree property.

The Bluetooth bindings clearly states that the address should be
specified in little-endian order, but due to a long-standing bug in the
Qualcomm driver which reversed the address some boot firmware has been
providing the address in big-endian order instead.

The only device out there that should be affected by this is the WCN3991
used in some Chromebooks.

Add a 'qcom,local-bd-address-broken' property which can be set on these
platforms to indicate that the boot firmware is using the wrong byte
order.

Note that ChromeOS always updates the kernel and devicetree in lockstep
so that there is no need to handle backwards compatibility with older
devicetrees.

5e74df2f8f A set of x86 fixes: 
- Ensure that the encryption mask at boot is properly propagated on
     5-level page tables, otherwise the PGD entry is incorrectly set to
     non-encrypted, which causes system crashes during boot.
 
   - Undo the deferred 5-level page table setup as it cannot work with
     memory encryption enabled.
 
   - Prevent inconsistent XFD state on CPU hotplug, where the MSR is reset
     to the default value but the cached variable is not, so subsequent
     comparisons might yield the wrong result and as a consequence the
     result prevents updating the MSR.
 
   - Register the local APIC address only once in the MPPARSE enumeration to
     prevent triggering the related WARN_ONs() in the APIC and topology code.
 
   - Handle the case where no APIC is found gracefully by registering a fake
     APIC in the topology code. That makes all related topology functions
     work correctly and does not affect the actual APIC driver code at all.
 
   - Don't evaluate logical IDs during early boot as the local APIC IDs are
     not yet enumerated and the invoked function returns an error
     code. Nothing requires the logical IDs before the final CPUID
     enumeration takes place, which happens after the enumeration.
 
   - Cure the fallout of the per CPU rework on UP which misplaced the
     copying of boot_cpu_data to per CPU data so that the final update to
     boot_cpu_data got lost which caused inconsistent state and boot
     crashes.
 
   - Use copy_from_kernel_nofault() in the kprobes setup as there is no
     guarantee that the address can be safely accessed.
 
   - Reorder struct members in struct saved_context to work around another
     kmemleak false positive
 
   - Remove the buggy code which tries to update the E820 kexec table for
     setup_data as that is never passed to the kexec kernel.
 
   - Update the resource control documentation to use the proper units.
 
   - Fix a Kconfig warning observed with tinyconfig

   fake APIC in the topology code. That makes all related topology
   functions work correctly and does not affect the actual APIC driver
   code at all.

 - Don't evaluate logical IDs during early boot as the local APIC IDs
   are not yet enumerated and the invoked function returns an error
   code. Nothing requires the logical IDs before the final CPUID
   enumeration takes place, which happens after the enumeration.

 - Cure the fallout of the per CPU rework on UP which misplaced the
   copying of boot_cpu_data to per CPU data so that the final update to
   boot_cpu_data got lost which caused inconsistent state and boot
   crashes.

 - Use copy_from_kernel_nofault() in the kprobes setup as there is no
   guarantee that the address can be safely accessed.

 - Reorder struct members in struct saved_context to work around another
   kmemleak false positive

 - Remove the buggy code which tries to update the E820 kexec table for
   setup_data as that is never passed to the kexec kernel.

 - Update the resource control documentation to use the proper units.

 - Fix a Kconfig warning observed with tinyconfig

a8ed59a3a8 Documentation/x86: Document that resctrl bandwidth control units are MiB 
The memory bandwidth software controller uses 2^20 units rather than
10^6. See mbm_bw_count() which computes bandwidth using the "SZ_1M"
Linux define for 0x00100000.

Update the documentation to use MiB when describing this feature.
It's too late to fix the mount option "mba_MBps" as that is now an
established user interface.

bb41fe35dc Char/Misc and other driver subsystem updates for 6.9-rc1 
Here is the big set of char/misc and a number of other driver subsystem
 updates for 6.9-rc1.  Included in here are:
   - IIO driver updates, loads of new ones and evolution of existing ones
   - coresight driver updates
   - const cleanups for many driver subsystems
   - speakup driver additions
   - platform remove callback void cleanups
   - mei driver updates
   - mhi driver updates
   - cdx driver updates for MSI interrupt handling
   - nvmem driver updates
   - other smaller driver updates and cleanups, full details in the
     shortlog
 
 All of these have been in linux-next for a long time with no reported
 issue, other than a build warning with some older versions of gcc for a
 speakup driver, fix for that will come in a few days when I catch up
 with my pending patch queues.
