acf1c3d68e bpf: Fix race between btf_put and btf_idr walk.
Florian and Eduard reported hard dead lock:
[   58.433327]  _raw_spin_lock_irqsave+0x40/0x50
[   58.433334]  btf_put+0x43/0x90
[   58.433338]  bpf_find_btf_id+0x157/0x240
[   58.433353]  btf_parse_fields+0x921/0x11c0

This happens since btf->refcount can be 1 at the time of btf_put() and
btf_put() will call btf_free_id() which will try to grab btf_idr_lock
and will dead lock.
Avoid the issue by doing btf_put() without locking.

93822f5161 hwmon: (pmbus/fsp-3y) Fix functionality bitmask in FSP-3Y YM-2151E
The bit flags in pmbus_driver_info functionality for YM-2151E chip were
joined with a comma operator instead of a bitwise OR. This means that
the last constant PMBUS_HAVE_IIN was not OR-ed with the other
PM_BUS_HAVE_* constants for this page but it initialized the next element
of the func array (which was not accessed from anywhere because of the
number of pages).

However, there is no need for setting PMBUS_HAVE_IIN in the 5Vsb page
because this command does not seem to be paged. Obviously, the device
only has one IIN sensor, so it doesn't make sense to query it again from
the second page.

On DT unaware platforms of_property_read_u32_array() returns -ENOSYS

19692f17cd hwmon: (aquacomputer_d5next) Add support for Aquacomputer Aquastream XT
Extend aquacomputer_d5next driver to expose various hardware sensors of the
Aquacomputer Aquastream XT watercooling pump, which communicates
through a proprietary USB HID protocol. Implemented by Leonard Anderweit
[1] [2].

Coolant temp, fan IC and external temp sensor readings are available, along
with speed and voltage of both the pump and optionally connected fan.
It also exposes pump current.

Additionally, serial number and firmware version are exposed through
debugfs.

spi: Add TPM HW flow flag
TPM specification [1] defines flow control over SPI. Client device can
insert a wait state on MISO when address is transmitted by controller
on MOSI. Detecting the wait state in software is only possible for
full duplex controllers. For controllers that support only half-
duplex, the wait state detection needs to be implemented in hardware.

Add a flag SPI_TPM_HW_FLOW for TPM device to set when software flow
control is not possible and hardware flow control is expected from
SPI controller.

f7abf14f00 posix-cpu-timers: Implement the missing timer_wait_running callback
For some unknown reason the introduction of the timer_wait_running callback
missed to fixup posix CPU timers, which went unnoticed for almost four years.
Marco reported recently that the WARN_ON() in timer_wait_running()
triggers with a posix CPU timer test case.

Posix CPU timers have two execution models for expiring timers depending on
CONFIG_POSIX_CPU_TIMERS_TASK_WORK:

1) If not enabled, the expiry happens in hard interrupt context so
   spin waiting on the remote CPU is reasonably time bound.

   Implement an empty stub function for that case.

2) If enabled, the expiry happens in task work before returning to user
   space or guest mode. The expired timers are marked as firing and moved
   from the timer queue to a local list head with sighand lock held. Once
   the timers are moved, sighand lock is dropped and the expiry happens in
   fully preemptible context. That means the expiring task can be scheduled
   out, migrated, interrupted etc. So spin waiting on it is more than
   suboptimal.

   The timer wheel has a timer_wait_running() mechanism for RT, which uses
   a per CPU timer-base expiry lock which is held by the expiry code and the
   task waiting for the timer function to complete blocks on that lock.

   This does not work in the same way for posix CPU timers as there is no
   timer base and expiry for process wide timers can run on any task
   belonging to that process, but the concept of waiting on an expiry lock
   can be used too in a slightly different way:

    - Add a mutex to struct posix_cputimers_work. This struct is per task
      and used to schedule the expiry task work from the timer interrupt.

    - Add a task_struct pointer to struct cpu_timer which is used to store
      a the task which runs the expiry. That's filled in when the task
      moves the expired timers to the local expiry list. That's not
      affecting the size of the k_itimer union as there are bigger union
      members already

    - Let the task take the expiry mutex around the expiry function

    - Let the waiter acquire a task reference with rcu_read_lock() held and
      block on the expiry mutex

   This avoids spin-waiting on a task which might not even be on a CPU and
   works nicely for RT too.

8f7f1b020e drm/amd/display: fix flickering caused by S/G mode
Currently, on a handful of ASICs. We allow the framebuffer for a given
plane to exist in either VRAM or GTT. However, if the plane's new
framebuffer is in a different memory domain than it's previous
framebuffer, flipping between them can cause the screen to flicker. So,
to fix this, don't perform an immediate flip in the aforementioned case.

[Why]
The bit for flip addr is being set causing the determination for
FAST vs MEDIUM to always return MEDIUM when plane info is provided
as a surface update. This causes extreme stuttering for the typical
atomic update path on Linux.

[How]
Don't use update_flags->raw for determining FAST vs MEDIUM. It's too
fragile to changes like this.

Explicitly specify the update type per update flag instead. It's not
as clever as checking the bits itself but at least it's correct.

58e67bb3c1 drm/amd/display: fix dpms_off issue when disabling bios mode
[Why]
disable_vbios_mode_if_required() will set dpms_off to false during boot
when pixel clk dismatches with driver requires. This will cause extra
backlight on and off if OS call 2 times setmode.

[How]
Set dpms_off to true to keep power_off and let OS control backlight by
display's powerState.

[Why]
Currently driver enables dmub outbox notification before oubox ISR is
registered. During boot scenario, sometimes dmub issues hpd outbox
message before driver registers ISR and those messages are missed.

[How]
Enable dmub outbox notification after outbox ISR is registered. Also,
restructured outbox enable code to call from dm layer and renamed APIs.

For smu v13_0_2, if the GPU supports xgmi, refer to

it will run gpu recover in AMDGPU_RESET_FOR_DEVICE_REMOVE mode when removing,
which makes all devices in hive list have hw reset but no resume except the
basic ip blocks, then other ip blocks will not call .hw_fini according to
ip_block.status.hw.

Since psp_free_shared_bufs just includes some software operations, so move
it to psp_sw_fini.
