45dd9bc75d KVM: SVM: hyper-v: placate modpost section mismatch error
modpost reports section mismatch errors/warnings:
WARNING: modpost: vmlinux.o: section mismatch in reference: svm_hv_hardware_setup (section: .text) -> (unknown) (section: .init.data)
WARNING: modpost: vmlinux.o: section mismatch in reference: svm_hv_hardware_setup (section: .text) -> (unknown) (section: .init.data)
WARNING: modpost: vmlinux.o: section mismatch in reference: svm_hv_hardware_setup (section: .text) -> (unknown) (section: .init.data)

This "(unknown) (section: .init.data)" all refer to svm_x86_ops.

Tag svm_hv_hardware_setup() with __init to fix a modpost warning as the
non-stub implementation accesses __initdata (svm_x86_ops), i.e. would
generate a use-after-free if svm_hv_hardware_setup() were actually invoked
post-init.  The helper is only called from svm_hardware_setup(), which is
also __init, i.e. lack of __init is benign other than the modpost warning.

064d7dcf51 sound updates for 6.3-rc1
The majority of works in this cycle are about ASoC spread over trees.
 Most of them are for new devices and cleanups / refactoring works,
 and not much significant changes are seen in the core side.
 Below are some highlights:
 
 ASoC:
 - Continued refactoring to move into common helper functions
 - Lots of DT schema conversons and stylistic nits
 - Continued work on building out the new SOF IPC4 scheme
 - Continued work for Intel AVS
 - New drivers for Awinc AT88395, Infineon PEB2466, Iron Device
   SMA1303, Mediatek MT8188, Realtek RT712, Renesas IDT821034,
   Samsung/Tesla FSD SoC I2S, and TI TAS5720A-Q1
 
 ALSA:
 - A few cleanups to make the remove callbacks to void returns
 - FireWire refactoring and enhancements
 - PCM kselftest enhancements

6ba912f1c0 kcsan: select CONFIG_CONSTRUCTORS
Building a kcsan enabled kernel for x86_64 with gcc-11 results in a lot

The same thing has been reported for mips64. I can't reproduce it for
any other compiler version, so I don't know if constructors are always
required here or if this is a gcc-11 specific implementation detail.

I see no harm in always enabling constructors here, and this reliably
fixes the build warnings for me.

f3dd0c5337 bpf: add missing header file include
Commit 74e19ef0ff ("uaccess: Add speculation barrier to
copy_from_user()") built fine on x86-64 and arm64, and that's the extent
of my local build testing.

It turns out those got the <linux/nospec.h> include incidentally through
other header files (<linux/kvm_host.h> in particular), but that was not
true of other architectures, resulting in build errors

  kernel/bpf/core.c: In function ‘___bpf_prog_run’:

RISC-V: add a spin_shadow_stack declaration

../arch/riscv/kernel/traps.c:335:15: warning: symbol 'spin_shadow_stack' was not declared. Should it be static?

However, this is used in entry.S and therefore shouldn't be static.
The same applies to the shadow_stack that this pseudo spinlock is
trying to protect, so do like its charge and add a declaration to
thread_info.h

deaeeda205 backlight: pwm_bl: Don't rely on a disabled PWM emiting inactive state
Most but not all PWMs drive the PWM pin to its inactive state when
disabled. However if there is no enable_gpio and no regulator the PWM
must drive the inactive state to actually disable the backlight.

So keep the PWM on in this case.

Note that to determine if there is a regulator some effort is required
because it might happen that there isn't actually one but the regulator
core gave us a dummy. (A nice side effect is that this makes the
regulator actually optional even on fully constrained systems.)

This fixes backlight disabling e.g. on i.MX6 when an inverted PWM is
used.

Hint for the future: If this change results in a regression, the bug is
in the lowlevel PWM driver.

00e7e698bf backlight: pwm_bl: Configure pwm only once per backlight toggle
When the function pwm_backlight_update_status() was called with
brightness > 0, pwm_get_state() was called twice (once directly and once
in compute_duty_cycle). Also pwm_apply_state() was called twice (once in
pwm_backlight_power_on() and once directly).

Optimize this to do both calls only once.

Note that with this affects the order of regulator and PWM setup. It's
not expected to have a relevant effect on hardware. The rationale for
this is that the regulator (and the GPIO) are reasonable to switch in
pwm_backlight_power_on()/pwm_backlight_power_off() but the PWM has
nothing to do with power. (The post_pwm_on_delay and pwm_off_delay are
still there though.)

fef0b89a45 backlight: arcxcnn: Use backlight helper
Instead of retrieving the backlight brightness in struct
backlight_properties manually, and then checking whether the backlight
should be on at all, use backlight_get_brightness() which does all
this and insulates this from future changes.

81bc9eada9 backlight: ktd253: Switch to use dev_err_probe() helper
In the probe path, dev_err() can be replaced with dev_err_probe()
which will check if error code is -EPROBE_DEFER and prints the
error name. It also sets the defer probe reason which can be
checked later through debugfs. It's more simple in error path.

Initial support of HID-BPF (Benjamin Tissoires)

The history is a little long for this series, as it was intended to be
sent for v6.2. However some last minute issues forced us to postpone it
to v6.3.

Conflicts:
* drivers/hid/i2c-hid/Kconfig:
  commit bf7660dab3 ("HID: stop drivers from selecting CONFIG_HID")
  conflicts with commit 2afac81dd1 ("HID: fix I2C_HID not selected
  when I2C_HID_OF_ELAN is")
  the resolution is simple enough: just drop the "default" and "select"
  lines as the new commit from Arnd is doing

7d1e3bd948 mfd: syscon: Allow reset control for syscon devices
Simple syscon devices may require deassertion of a reset signal in order
to access their register set. Rather than requiring a custom driver to
implement this, we can use the generic "resets" specifiers to link a
reset line to the syscon.

This change adds an optional reset line to the syscon device
description, and deasserts the reset if detected.

to access their register set. This change adds the `resets` property from
reset.yaml#/properties/resets (referenced through core.yaml), specifying
a maxItems of 1 for a single (optional) reset descriptor.

This will allow a future change to the syscon driver to implement reset
control.

This removes a layer of indirection through pm_power_off() and allows
the PMIC handler to be used as a fallback when firmware power off fails.
This happens on boards like the Clockwork DevTerm R-01 where OpenSBI
does not know how to use the PMIC to power off the board.

Move the check for AXP288 to avoid registering a dummy handler.
