27af31e449 hrtimers: Mark is_migration_base() with __always_inline
When is_migration_base() is unused, it prevents kernel builds
with clang, `make W=1` and CONFIG_WERROR=y:

kernel/time/hrtimer.c:156:20: error: unused function 'is_migration_base' [-Werror,-Wunused-function]
  156 | static inline bool is_migration_base(struct hrtimer_clock_base *base)
      |                    ^~~~~~~~~~~~~~~~~

Fix this by marking it with __always_inline.

[ tglx: Use __always_inline instead of __maybe_unused and move it into the
  	usage sites conditional ]

fa3595523d io_uring: get rid of alloc cache init_once handling
init_once is called when an object doesn't come from the cache, and
hence needs initial clearing of certain members. While the whole
struct could get cleared by memset() in that case, a few of the cache
members are large enough that this may cause unnecessary overhead if
the caches used aren't large enough to satisfy the workload. For those
cases, some churn of kmalloc+kfree is to be expected.

Ensure that the 3 users that need clearing put the members they need
cleared at the start of the struct, and wrap the rest of the struct in
a struct group so the offset is known.

While at it, improve the interaction with KASAN such that when/if
KASAN writes to members inside the struct that should be retained over
caching, it won't trip over itself. For rw and net, the retaining of
the iovec over caching is disabled if KASAN is enabled. A helper will
free and clear those members in that case.

really should be using a READ_ONCE() as ->sqe may still be pointing to
the original SQE. Since the prep side already does this READ_ONCE() and
stores it locally, use that value rather than re-read it.

ee59e3820c nvme-fc: do not ignore connectivity loss during connecting
When a connectivity loss occurs while nvme_fc_create_assocation is
being executed, it's possible that the ctrl ends up stuck in the LIVE
state:

  1) nvme nvme10: NVME-FC{10}: create association : ...
  2) nvme nvme10: NVME-FC{10}: controller connectivity lost.
                  Awaiting Reconnect
     nvme nvme10: queue_size 128 > ctrl maxcmd 32, reducing to maxcmd
  3) nvme nvme10: Could not set queue count (880)
     nvme nvme10: Failed to configure AEN (cfg 900)
  4) nvme nvme10: NVME-FC{10}: controller connect complete
  5) nvme nvme10: failed nvme_keep_alive_end_io error=4

A connection attempt starts 1) and the ctrl is in state CONNECTING.
Shortly after the LLDD driver detects a connection lost event and calls
nvme_fc_ctrl_connectivity_loss 2). Because we are still in CONNECTING
state, this event is ignored.

nvme_fc_create_association continues to run in parallel and tries to
communicate with the controller and these commands will fail. Though
these errors are filtered out, e.g in 3) setting the I/O queues numbers
fails which leads to an early exit in nvme_fc_create_io_queues. Because
the number of IO queues is 0 at this point, there is nothing left in
nvme_fc_create_association which could detected the connection drop.
Thus the ctrl enters LIVE state 4).

Eventually the keep alive handler times out 5) but because nothing is
being done, the ctrl stays in LIVE state.

There is already the ASSOC_FAILED flag to track connectivity loss event
but this bit is set too late in the recovery code path. Move this into
the connectivity loss event handler and synchronize it with the state
change. This ensures that the ASSOC_FAILED flag is seen by
nvme_fc_create_io_queues and it does not enter the LIVE state after a
connectivity loss event. If the connectivity loss event happens after we
entered the LIVE state the normal error recovery path is executed.

294b2b7516 nvme: handle connectivity loss in nvme_set_queue_count
When the set feature attempts fails with any NVME status code set in
nvme_set_queue_count, the function still report success. Though the
numbers of queues set to 0. This is done to support controllers in
degraded state (the admin queue is still up and running but no IO
queues).

Though there is an exception. When nvme_set_features reports an host
path error, nvme_set_queue_count should propagate this error as the
connectivity is lost, which means also the admin queue is not working
anymore.

d3d380eded nvme-fc: go straight to connecting state when initializing
The initial controller initialization mimiks the reconnect loop
behavior by switching from NEW to RESETTING and then to CONNECTING.

The transition from NEW to CONNECTING is a valid transition, so there is
no point entering the RESETTING state. TCP and RDMA also transition
directly to CONNECTING state.

ab16714fcb tools/rtla: Add basic test suite
Implement a simple TAP-based test engine in bash and a few basic tests
using it, to be used to check for bugs and regressions.

A new "check" target is added to the rtla Makefile that runs the test suite
using the "prove" command implemented by Test::Harness.

The only test format currently supported is running rtla with defined
command arguments per test, checking its exit code. In case the exit
code is non-zero, the output of rtla is displayed, together with the
exit code.

The test cases are adopted from rtla tests in the Continuous Kernel
Integration (CKI) project [1] with the authors' approval.

8259cb14a7 rv: Reset per-task monitors also for idle tasks
RV per-task monitors are implemented through a monitor structure
available for each task_struct. This structure is reset every time the
monitor is (re-)started, to avoid inconsistencies if the monitor was
activated previously.
To do so, we reset the monitor on all threads using the macro
for_each_process_thread. However, this macro excludes the idle tasks on
each CPU. Idle tasks could be considered tasks on their own right and it
should be up to the model whether to ignore them or not.

Reset monitors also on the idle tasks for each present CPU whenever we
reset all per-task monitors.

4453f36086 PCI: Batch BAR sizing operations
Toggling memory enable is free on bare metal, but potentially expensive
in virtualized environments as the device MMIO spaces are added and
removed from the VM address space, including DMA mapping of those spaces
through the IOMMU where peer-to-peer is supported.  Currently memory
decode is disabled around sizing each individual BAR, even for SR-IOV
BARs while VF Enable is cleared.

This can be better optimized for virtual environments by sizing a set
of BARs at once, stashing the resulting mask into an array, while only
toggling memory enable once.  This also naturally improves the SR-IOV
path as the caller becomes responsible for any necessary decode disables
while sizing BARs, therefore SR-IOV BARs are sized relying only on the
VF Enable rather than toggling the PF memory enable in the command
register.

Merge tag 'bpf-next-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next

Pull bpf updates from Alexei Starovoitov:
 "A smaller than usual release cycle.

  The main changes are:

   - Prepare selftest to run with GCC-BPF backend (Ihor Solodrai)

     In addition to LLVM-BPF runs the BPF CI now runs GCC-BPF in compile
     only mode. Half of the tests are failing, since support for
     btf_decl_tag is still WIP, but this is a great milestone.

   - Convert various samples/bpf to selftests/bpf/test_progs format
     (Alexis Lothoré and Bastien Curutchet)

   - Teach verifier to recognize that array lookup with constant
     in-range index will always succeed (Daniel Xu)

   - Cleanup migrate disable scope in BPF maps (Hou Tao)

   - Fix bpf_timer destroy path in PREEMPT_RT (Hou Tao)

   - Always use bpf_mem_alloc in bpf_local_storage in PREEMPT_RT (Martin
     KaFai Lau)

   - Refactor verifier lock support (Kumar Kartikeya Dwivedi)

     This is a prerequisite for upcoming resilient spin lock.

   - Remove excessive 'may_goto +0' instructions in the verifier that
     LLVM leaves when unrolls the loops (Yonghong Song)

   - Remove unhelpful bpf_probe_write_user() warning message (Marco
     Elver)

   - Add fd_array_cnt attribute for prog_load command (Anton Protopopov)

     This is a prerequisite for upcoming support for static_branch"

28a9972e0f wifi: ath12k: fix skb_ext_desc leak in ath12k_dp_tx() error path
When vlan support was added, we missed that when
ath12k_dp_prepare_htt_metadata() returns an error we also need to free
the skb holding the metadata before going on with the cleanup process.

Compile tested only.

754916d4a2 capabilities patches for 6.14-rc1
This branch contains basically the same two patches as last time:
 
 1. A patch by Paul Moore to remove the cap_mmap_file() hook, as it simply
    returned the default return value and so doesn't need to exist.
 2. A patch by Jordan Rome to add a trace event for cap_capable(), updated
    to address your feedback during the last cycle.
 
 Both patches have been sitting in linux-next since 6.13-rc1 with no
 issues.

ASoC: Intel: bytcr_rt5640: Add DMI quirk for Vexia Edu Atla 10 tablet 5V
The Vexia EDU ATLA 10 tablet comes in 2 different versions with
significantly different mainboards. The only outward difference is that
the charging barrel on one is marked 5V and the other is marked 9V.

The 5V version mostly works with the BYTCR defaults, except that it is
missing a CHAN package in its ACPI tables and the default of using
SSP0-AIF2 is wrong, instead SSP0-AIF1 must be used. That and its jack
detect signal is not inverted as it usually is.

Add a DMI quirk for the 5V version to fix sound not working.

752b6e3af3 pwm: microchip-core: fix incorrect comparison with max period
In mchp_core_pwm_apply_locked(), if hw_period_steps is equal to its max,
an error is reported and .apply fails. The max value is actually a
permitted value however, and so this check can fail where multiple
channels are enabled.

For example, the first channel to be configured requests a period that
sets hw_period_steps to the maximum value, and when a second channel
is enabled the driver reads hw_period_steps back from the hardware and
finds it to be the maximum possible value, triggering the warning on a
permitted value. The value to be avoided is 255 (PERIOD_STEPS_MAX + 1),
as that will produce undesired behaviour, so test for greater than,
rather than equal to.

syzbot found that calling mr_mfc_uses_dev() for unres entries
would crash [1], because c->mfc_un.res.minvif / c->mfc_un.res.maxvif
alias to "struct sk_buff_head unresolved", which contain two pointers.

A regression was caused by commit e4b5ccd392 ("drm/v3d: Ensure job
pointer is set to NULL after job completion"), but this commit is not
yet in next-fixes, fast-forward it.

Note that this recreates Linus merge in 96c84703f1 ("Merge tag

because I didn't want to backmerge a random point in the merge window.
