453eda46b7 lib/crypto: x86/blake2s: Reduce size of BLAKE2S_SIGMA2
Save 480 bytes of .rodata by replacing the .long constants with .bytes,
and using the vpmovzxbd instruction to expand them.

Also update the code to do the loads before incrementing %rax rather
than after.  This avoids the need for the first load to use an offset.

13cecc526d lib/crypto: chacha: Consolidate into single module
Consolidate the ChaCha code into a single module (excluding
chacha-block-generic.c which remains always built-in for random.c),
similar to various other algorithms:

- Each arch now provides a header file lib/crypto/$(SRCARCH)/chacha.h,
  replacing lib/crypto/$(SRCARCH)/chacha*.c.  The header defines
  chacha_crypt_arch() and hchacha_block_arch().  It is included by
  lib/crypto/chacha.c, and thus the code gets built into the single
  libchacha module, with improved inlining in some cases.

- Whether arch-optimized ChaCha is buildable is now controlled centrally
  by lib/crypto/Kconfig instead of by lib/crypto/$(SRCARCH)/Kconfig.
  The conditions for enabling it remain the same as before, and it
  remains enabled by default.

- Any additional arch-specific translation units for the optimized
  ChaCha code, such as assembly files, are now compiled by
  lib/crypto/Makefile instead of lib/crypto/$(SRCARCH)/Makefile.

This removes the last use for the Makefile and Kconfig files in the
arm64, mips, powerpc, riscv, and s390 subdirectories of lib/crypto/.  So
also remove those files and the references to them.

Rename libchacha.c to chacha.c to make the naming consistent with other
algorithms and allow additional source files to be added to the
libchacha module.  This file currently contains chacha_crypt_generic(),
but it will soon be updated to contain chacha_crypt().

9dd6bb667e crypto: chacha - register only "-lib" drivers
For the "chacha20", "xchacha20", and "xchacha12" skcipher algorithms,
instead of registering "*-generic" drivers as well as conditionally
registering "*-$(ARCH)" drivers, instead just register "*-lib" drivers.
These just use the regular library functions, so they just do the right
thing and are fully accelerated when supported by the CPU.

This eliminates the need for the ChaCha library to support
chacha_crypt_generic() and hchacha_block_generic() as part of its
external interface.  A later commit will make chacha_crypt_generic() a
static function.

Since this commit removes several "*-generic" driver names which
crypto/testmgr.c expects to exist, update testmgr.c accordingly.

- Each arch now provides a header file lib/crypto/$(SRCARCH)/poly1305.h,
  replacing lib/crypto/$(SRCARCH)/poly1305*.c.  The header defines
  poly1305_block_init(), poly1305_blocks(), poly1305_emit(), and
  optionally poly1305_mod_init_arch().  It is included by
  lib/crypto/poly1305.c, and thus the code gets built into the single
  libpoly1305 module, with improved inlining in some cases.

- Whether arch-optimized Poly1305 is buildable is now controlled
  centrally by lib/crypto/Kconfig instead of by
  lib/crypto/$(SRCARCH)/Kconfig.  The conditions for enabling it remain
  the same as before, and it remains enabled by default.  (The PPC64 one
  remains unconditionally disabled due to 'depends on BROKEN'.)

- Any additional arch-specific translation units for the optimized
  Poly1305 code, such as assembly files, are now compiled by
  lib/crypto/Makefile instead of lib/crypto/$(SRCARCH)/Makefile.

A special consideration is needed because the Adiantum code uses the
poly1305_core_*() functions directly.  For now, just carry forward that
approach.  This means retaining the CRYPTO_LIB_POLY1305_GENERIC kconfig
symbol, and keeping the poly1305_core_*() functions in separate
translation units.  So it's not quite as streamlined I've done with the
other hash functions, but we still get a single libpoly1305 module.

Note: to see the diff from the arm, arm64, and x86 .c files to the new
.h files, view this commit with 'git show -M10'.

0ef5c4e4db nouveau: fix disabling the nonstall irq due to storm code
Nouveau has code that when it gets an IRQ with no allowed handler
it disables it to avoid storms.

However with nonstall interrupts, we often disable them from
the drm driver, but still request their emission via the push submission.

Just don't disable nonstall irqs ever in normal operation, the
event handling code will filter them out, and the driver will
just enable/disable them at load time.

This fixes timeouts we've been seeing on/off for a long time,
but they became a lot more noticeable on Blackwell.

This doesn't fix all of them, there is a subsequent fence emission
fix to fix the last few.

214ae22e6d rpmsg: core: Drop dev_pm_domain_detach() call
Starting with commit f99508074e ("PM: domains: Detach on
device_unbind_cleanup()"), there is no longer a need to call
dev_pm_domain_detach() in the bus remove function. The
device_unbind_cleanup() function now handles this to avoid
invoking devres cleanup handlers while the PM domain is
powered off, which could otherwise lead to failures as
described in the above-mentioned commit.

Drop the explicit dev_pm_domain_detach() call and rely instead
on the flags passed to dev_pm_domain_attach() to power off the
domain.

a8b79b0918 drm/amd: Re-enable common modes for eDP and LVDS
[Why]
Although compositors will add their own modes, Xorg won't use it's own
modes and will only stick to modes advertised by the driver. This mean a
user that used to pick 1024x768 could no longer access it unless the
panel's native resolution was 1024x768.

[How]
Revert commit 6d396e7ac1 ("drm/amd/display: Disable common modes for
LVDS") and commit 7948afb46a ("drm/amd/display: Disable common modes
for eDP").

The panel will still use scaling for any non-native modes due to

Update the legacy (non-DC) display code to respect the maximum
pixel clock for HDMI and DVI-D. Reject modes that would require
a higher pixel clock than can be supported.

Also update the maximum supported HDMI clock value depending on
the ASIC type.

For reference, see the DC code:
check max_hdmi_pixel_clock in dce*_resource.c

v2:
Fix maximum clocks for DVI-D and DVI/HDMI adapters.

16f2e14ee9 drm/amd/display: Skip Check Runtime Link Setting for Specific Branch Device
[why]
Read link setting inside mode validation is not always the final downlink setting.
It is found true in Synaptics branch device.

At bootup, the preferred mode being set right after 1080p is set. It occurred
before graphic load. That modeset switch in a short period of time makes
the branch device switch back and forth from lower and higher link rate,
observed at Synaptics branch device.
DP2 RTK hub on the other hand, sticks to highest available downlink rate after bootup.

Existing check of runtime downlink setting in mode validation shows asynchronous at
branch device link switch, i.e., downlink switch to higher link rate not yet complete
when the mode validation tries to probe the downlink setting. That makes mode validation
checking downlink setting making wrong decision by pruning modes that should pass the
validation after the downlink setting switch is complete.

[how]
If Synaptics is found at the last branch, skip checking downlink setting
at mode validation.

[Why & How]
Previously, when calculating dto phase, we would incorrectly fail when phase
<=0 without additionally checking for the integer value. This meant that
calculations would incorrectly fail when the desired pixel clock was an exact
multiple of the reference clock.

cf49a454e1 drm/amd/display: Add Component To Handle Bounding Box Values and IP Caps
[Why]
Bounding box values can be stored in multiple locations. (e.g. PMFW, VBIOS, DMUB).
The source and interpretation of these values can vary with DCN revision
so there should be a component that can gather these values and translate
them accordingly

[How]
Have component start with the statically defined values as a base.
Then update them as needed with DCN-specific logic
Guard this component with FPU flags since values need to be in float point.

c2fbf72fe3 drm/amd: Re-enable common modes for eDP and LVDS
[Why]
Although compositors will add their own modes, Xorg won't use it's own
modes and will only stick to modes advertised by the driver. This mean a
user that used to pick 1024x768 could no longer access it unless the
panel's native resolution was 1024x768.

[How]
Revert commit 6d396e7ac1 ("drm/amd/display: Disable common modes for
LVDS") and commit 7948afb46a ("drm/amd/display: Disable common modes
for eDP").

The panel will still use scaling for any non-native modes due to
commit 978fa2f6d0 ("drm/amd/display: Use scaling for non-native
resolutions on eDP")

9c0442286f drm/amdgpu: Check vcn state before profile switch
The patch uses power state of VCN instances for requesting video
profile.

In idle worker of a vcn instance, when there is no outstanding
submisssion or fence, the instance is put to power gated state. When
all instances are powered off that means video profile is no longer
required. A request is made to turn off video profile.

A job submission starts with begin_use of ring, and at that time
vcn instance state is changed to power on. Subsequently a check is
made for active video profile, and if not active, a request is made.
