e3a89cc281 rust: device: Add property_present()
This implements Device::property_present(), which calls C APIs
device_property_present() helper.

The new helper will be used by Rust based cpufreq drivers.

778c29fca7 drm/i915: Extract intel_crtc_vblank_delay()
Pull the vblank delay computation into a separate function.
We'll need more logic here soon and we don't want to pollute
intel_crtc_compute_config() with low level details.

We'll use HAS_DSB() to determine if any delay might be required
or not because delayed vblank only really exists for the
purposes of the DSB. It also doesn't event exists on any pre-tgl
platforms, which also don't have DSB. I was midly tempted
to check for the enable_dsb modparam here actually, but as
that can be changed dynamically via debugfs we'd need to either
reconfigure it on the fly or force a modeset. Neither will happen
currently, so we'll just assume DSB may be used of the platform
supports it.

8c4840277b signal/posixtimers: Handle ignore/blocked sequences correctly
syzbot triggered the warning in posixtimer_send_sigqueue(), which warns
about a non-ignored signal being already queued on the ignored list.

The warning is actually bogus, as the following sequence causes this:

    signal($SIG, SIGIGN);
    timer_settime(...);			// arm periodic timer

      timer fires, signal is ignored and queued on ignored list

    sigprocmask(SIG_BLOCK, ...);        // block the signal
    timer_settime(...);			// re-arm periodic timer

      timer fires, signal is not ignored because it is blocked
        ---> Warning triggers as signal is on the ignored list

Ideally timer_settime() could remove the signal, but that's racy and
incomplete vs. other scenarios and requires a full reevaluation of the
pending signal list.

Instead of adding more complexity, handle it gracefully by removing the
warning and requeueing the signal to the pending list. That's correct
versus:

  1) sig[timed]wait() as that does not check for SIGIGN and only relies on
     dequeue_signal() -> posixtimers_deliver_signal() to check whether the
     pending signal is still valid.

  2) Unblocking of the signal.

     - If the unblocking happens before SIGIGN is replaced by a signal
       handler, then the timer is rearmed in dequeue_signal(), but
       get_signal() will ignore it. The next timer expiry will move it back
       to the ignored list.

     - If SIGIGN was replaced before unblocking, then the signal will be
       delivered and a subsequent expiry will queue a signal on the pending
       list again.

There is a related scenario to trigger the complementary warning in the
signal ignored path, which does not expect the signal to be on the pending
list when it is ignored. That can be triggered even before the above change
via:

task1			task2

signal($SIG, SIGIGN);
			sigprocmask(SIG_BLOCK, ...);

timer_create();		// Signal target is task2
timer_settime(...);	// arm periodic timer

   timer fires, signal is not ignored because it is blocked
   and queued on the pending list of task2

       	      	     	syscall()
			   // Sets the pending flag
			   sigprocmask(SIG_UNBLOCK, ...);

			-> preemption, task2 cannot dequeue the signal

timer_settime(...);	// re-arm periodic timer

   timer fires, signal is ignored
        ---> Warning triggers as signal is on task2's pending list
	     and the thread group is not exiting

Consequently, remove that warning too and just keep the signal on the
pending list.

The following attempt to deliver the signal on return to user space of
task2 will ignore the signal and a subsequent expiry will bring it back to
the ignored list, if it did not get blocked or un-ignored before that.

syscon_regmap_lookup_by_phandle() and getting the argument.  Except

There is also no real benefit in printing errors on missing syscon
argument, because this is done just too late: runtime check on
static/build-time data.  Dtschema and Devicetree bindings offer the
static/build-time check for this already.

72bb8275a3 reset: amlogic: aux: drop aux registration helper
Having the aux registration helper along with the registered driver is not
great dependency wise. It does not allow the registering driver to be
properly decoupled from the registered auxiliary driver.

Drop the registration helper from the amlogic auxiliary reset driver.
This will be handled in the registering clock driver to start with while
a more generic solution is worked on.

5d1f7ee7f0 block: Change blk_stack_atomic_writes_limits() unit_min check
The current check in blk_stack_atomic_writes_limits() for a bottom device
supporting atomic writes is to verify that limit atomic_write_unit_min is
non-zero.

This would cause a problem for device mapper queue limits calculation. This
is because it uses a temporary queue_limits structure to stack the limits,
before finally commiting the limits update.
The value of atomic_write_unit_min for the temporary queue_limits
structure is never evaluated and so cannot be used, so use limit
atomic_write_hw_unit_min.

7c54803863 KVM: x86/mmu: Return RET_PF* instead of 1 in kvm_mmu_page_fault()
Return RET_PF* (excluding RET_PF_EMULATE/RET_PF_CONTINUE/RET_PF_INVALID)
instead of 1 in kvm_mmu_page_fault().

The callers of kvm_mmu_page_fault() are KVM page fault handlers (i.e.,
npf_interception(), handle_ept_misconfig(), __vmx_handle_ept_violation(),
kvm_handle_page_fault()). They either check if the return value is > 0 (as
in npf_interception()) or pass it further to vcpu_run() to decide whether
to break out of the kernel loop and return to the user when r <= 0.
Therefore, returning any positive value is equivalent to returning 1.

Warn if r == RET_PF_CONTINUE (which should not be a valid value) to ensure
a positive return value.

This is a preparation to allow TDX's EPT violation handler to check the
RET_PF* value and retry internally for RET_PF_RETRY.

No functional changes are intended.

The warning is triggered by the fact that there is still a
wireless_device linked to the wiphy we are unregistering, due to
wiphy_unregister() now being called after net device unregister (performed
in wilc_netdev_cleanup()). Fix this warning by moving wiphy_unregister()
after wilc_netdev_cleanup() is nominal paths (ie: driver removal).
wilc_netdev_cleanup() ordering is left untouched in error paths in probe
function because net device is not registered in those paths (so the
warning can not trigger), yet the wiphy can still be registered, and we
still some cleanup steps from wilc_netdev_cleanup().

26701574ce s390/futex: Fix FUTEX_OP_ANDN implementation
The futex operation FUTEX_OP_ANDN is supposed to implement

*(int *)UADDR2 &= ~OPARG;

The s390 implementation just implements an AND instead of ANDN.
Add the missing bitwise not operation to oparg to fix this.

This is broken since nearly 19 years, so it looks like user space is
not making use of this operation.

31691914c3 kunit: Introduce autorun option
The new option controls tests run on boot or module load. With the new
debugfs "run" dentry allowing to run tests on demand, an ability to disable
automatic tests run becomes a useful option in case of intrusive tests.

The option is set to true by default to preserve the existent behavior. It
can be overridden by either the corresponding module option or by the
corresponding config build option.

6f7a644eb7 io_uring/register: cache old SQ/CQ head reading for copies
The SQ and CQ ring heads are read twice - once for verifying that it's
within bounds, and once inside the loops copying SQE and CQE entries.
This is technically incorrect, in case the values could get modified
in between verifying them and using them in the copy loop. While this
won't lead to anything truly nefarious, it may cause longer loop times
for the copies than expected.

Read the ring head values once, and use the verified value in the copy
loops.

The wrong NVM causes poor RF performance, and effects user experience
for several types of laptop with WCN6855 on the market.

Fix by downloading board ID specific NVM if board ID is available.

f07d478090 Bluetooth: Get rid of cmd_timeout and use the reset callback
The hdev->reset is never used now and the hdev->cmd_timeout actually
does reset. This patch changes the call path from
  hdev->cmd_timeout -> vendor_cmd_timeout -> btusb_reset -> hdev->reset
, to
  hdev->reset -> vendor_reset -> btusb_reset
Which makes it clear when we export the hdev->reset to a wider usage
e.g. allowing reset from sysfs.

This patch doesn't introduce any behavior change.

Replace ternary (condition ? "enable" : "disable") syntax with helpers
from string_choices.h because:
1. Simple function call with one argument is easier to read.  Ternary
   operator has three arguments and with wrapping might lead to quite
   long code.
2. Is slightly shorter thus also easier to read.
3. It brings uniformity in the text - same string.
4. Allows deduping by the linker, which results in a smaller binary

5f397409f8 Bluetooth: L2CAP: handle NULL sock pointer in l2cap_sock_alloc
A NULL sock pointer is passed into l2cap_sock_alloc() when it is called
from l2cap_sock_new_connection_cb() and the error handling paths should
also be aware of it.

Seemingly a more elegant solution would be to swap bt_sock_alloc() and
l2cap_chan_create() calls since they are not interdependent to that moment
but then l2cap_chan_create() adds the soon to be deallocated and still
dummy-initialized channel to the global list accessible by many L2CAP
paths. The channel would be removed from the list in short period of time
but be a bit more straight-forward here and just check for NULL instead of
changing the order of function calls.

Found by Linux Verification Center (linuxtesting.org) with SVACE static
analysis tool.

b88655bc65 Bluetooth: btbcm: Fix NULL deref in btbcm_get_board_name()
devm_kstrdup() can return a NULL pointer on failure,but this
returned value in btbcm_get_board_name() is not checked.
Add NULL check in btbcm_get_board_name(), to handle kernel NULL
pointer dereference error.

30209aeff7 Bluetooth: qca: Expand firmware-name to load specific rampatch
The firmware-name property has been expanded to specify the names of NVM
and rampatch firmware for certain chips, such as the QCA6698 Bluetooth
chip. Although it shares the same IP core as the WCN6855, the QCA6698
has different RF components and RAM sizes, necessitating new firmware
files. This change allows for the configuration of NVM and rampatch in
DT.

Possible configurations:
firmware-name = QCA6698/hpnv21.bin, QCA6698/hpbtfw21.tlv;
firmware-name = QCA6698/hpnv21, QCA6698/hpbtfw21.tlv;

2c5aae129f io_uring/register: document io_register_resize_rings() shared mem usage
It can be a bit hard to tell which parts of io_register_resize_rings()
are operating on shared memory, and which ones are not. And anything
reading or writing to those regions should really use the read/write
once primitives.

Hence add those, ensuring sanity in how this memory is accessed, and
helping document the shared nature of it.

a4c5a468c6 Bluetooth: qca: Update firmware-name to support board specific nvm
Different connectivity boards may be attached to the same platform. For
example, QCA6698-based boards can support either a two-antenna or
three-antenna solution, both of which work on the sa8775p-ride platform.
Due to differences in connectivity boards and variations in RF
performance from different foundries, different NVM configurations are
used based on the board ID.

Therefore, in the firmware-name property, if the NVM file has an
extension, the NVM file will be used. Otherwise, the system will first
try the .bNN (board ID) file, and if that fails, it will fall back to
the .bin file.

Possible configurations:
firmware-name = "QCA6698/hpnv21";
firmware-name = "QCA6698/hpnv21.bin";

Expand the firmware-name property to specify the names of NVM and
rampatch firmware to load. This update will support loading specific
firmware (nvm and rampatch) for certain chips, like the QCA6698
Bluetooth chip, which shares the same IP core as the WCN6855 but has

We might use different connectivity boards on the same platform. For

b16b327edb Bluetooth: btusb: add sysfs attribute to control USB alt setting
When a Bluetooth raw socket is open, the HCI event related to SCO
connection changes are not dispatched to the hci_event module, and
the underlying Bluetooth controller's USB Interface 1 will not be
updated accordingly.

This patch adds `isoc_alt` sysfs attribute, allowing user space
to update the alternate setting of the USB interface alternate
setting as needed.
