This function is not called from anywhere anymore and
every implementation was bogus.
Some implementations checked busy flags of the IP blocks,
which are not really indicative of whether the block is
hung and needs to be reset. For example the blocks
could be busy just normally executing submissions,
and not need to be reset.
Other implementations checked IB tests, which is actually
more useful, but could still just indicate that an IP block
is executing submissions normally.
It is also unnecessary because the GPU recovery code path
already knows which ring is hung so we know exactly what
we need to reset.
Just delete check_soft_reset() entirely.

This was basically dead code, not used or called from anywhere.
Now that DC is the default display driver for all ASICs,
it is unlikely that anyone wants to develop this further.

We should only reset the memory controller during ASIC reset
and only when it's absolutely necessary. Otherwise, resetting
the memory controller typically just breaks everything and
on dGPUs may also clear the contents of VRAM (it's unclear if
it really does, but it's likely).
Specifically for GMC 8, the memory controller is reset as part
of the ASIC reset and otherwise should be left alone.

Soft reset means resetting IP blocks individually using
a hardware interconnect (SRBM or GRBM) without assistance
from firmware.
Soft reset is a useful tool for implementing GPU recovery,
eg. it is already successfully used for SDMA queue resets.
It should be used by a GPU recovery method instead of
being called directly from the ASIC reset code path.
Currently, this is only used on Carrizo and Stoney,
but doesn't work well and fails on those chips.
A subsequent commit will add a working GFX8 recovery
implementation after the cleanups.
Note that this commit only cleans up the ASIC reset path,
which also unblocks more opportunities for cleanup for
the various IP blocks. Those will be done in subsequent commits.

Soft recovery is not the same as soft reset:
* Soft recovery attempts to resolve a GPU hang by sending a
command to terminate shaders.
* Soft reset completely re-initializes an entire device IP block,
which may affect multiple rings and jobs at the same time.

The PKEY_VERIFYPROTK ioctl takes data from user-space and verifies the
contained protected key. While checking the integrity of the ioctl
request structure is the responsibility of the generic pkey_api code,
the verification of the contained protected key is the responsibility
of the pkey handler.
The keytype verification (based on the calculated bitsize of the key)
is part of the protected key verification and therefore the
responsibility of the pkey handler (which already verifies
it). Therefore the keytype verification is removed from the generic
pkey_api code.
As the calculation of the key bitsize is currently wrong, the removal
of the keytype check in pkey_api also removes this wrong
calculation. For this reason, the commit is flagged with the Fixes:
tag.

For SOC24 ASICs (RDNA4 / Navi 4x dGPUs) re-enabling PM features fails if an

commit df3c7dc5c58b ("drm/amdgpu: Reset dGPU if suspend got aborted")
commit 38e8ca3e4b6d ("amdgpu/soc15: enable asic reset for dGPU in case of suspend abort")
The aborted resume fails with:
amdgpu: SMU: No response msg_reg: 6 resp_reg: 0
amdgpu: Failed to enable requested dpm features!
amdgpu: resume of IP block <smu> failed -62
Apply the same workaround for soc24: detect the aborted-suspend state at
resume via the sign-of-life register and reset the device before re-init.
This is a workaround till a proper solution is finalized.

IDR is deprecated so let's replace it with xarray.
Conversion is mostly 1:1 apart from AMDGPU_BO_LIST_OP_UPDATE which was
implemented with idr_replace, and has now been replaced with a sequence of
xa_load and xa_cmpxchg. Should userspace attempt multi-threaded update
operations on the same handle it could theoretically hit a new -ENOENT
path. But I believe this is purely theoretical and still safe.
Also, since we have removed the RCU protection around the handle lookup we
also removed the RCU freeing of the list.

When the RAS core manages the EEPROM, the eeprom_control is never
initialized (amdgpu_ras_init_badpage_info() returns early), so reading
ras/ras_eeprom_table in debugfs printed only a zeroed header and no
records, even though bad-page records exist in the RAS core EEPROM.
Source the table header and records from the RAS core EEPROM
(ras_core->ras_eeprom) in that case, reusing the existing output layout
so the debugfs node keeps the same format. Skip the dump when the
firmware manages the EEPROM, since the records are not stored in the
I2C-backed table then.

Dropping the _sw_ part from the names was proposed multiple times now and
IIRC people generally agreed with the idea already.
The function requests a fence to signal and triggers some sort of HW
interaction on most backends.
So this is not really software related at all and the callback is already
just named enable_signaling as well.
Just streamline that and use a consistent name everywhere.

The common wc-ioremap carveout callbacks live in
remoteproc_internal.h, which is included by the remoteproc core.
This means the helper bodies are parsed even for builds that do not
enable any platform driver using those callbacks.
On s390, CONFIG_HAS_IOMEM and CONFIG_GENERIC_IOREMAP depend on
CONFIG_PCI. A randconfig with CONFIG_REMOTEPROC=y and CONFIG_PCI=n
therefore has no usable ioremap_wc() or iounmap() declarations, and
fails to build the common remoteproc objects with implicit declarations
from the helper bodies.
Only include linux/io.h and build the real wc-ioremap helpers when
CONFIG_HAS_IOMEM is enabled. Provide no-IOMEM stubs so the internal
header remains self-contained for randconfig and COMPILE_TEST coverage.
