So, if a user is using hardware rotated modes with PSR-SU enabled,

River reports boot hangs with v6.6 and v6.7, and the bisect points to
commit
a1b87d54f4 ("x86/efistub: Avoid legacy decompressor when doing EFI boot")
which moves the memory allocation and kernel decompression from the
legacy decompressor (which executes *after* ExitBootServices()) to the
EFI stub, using boot services for allocating the memory. The memory
allocation succeeds but the subsequent call to decompress_kernel() never
returns, resulting in a failed boot and a hanging system.
As it turns out, this issue only occurs when physical address
randomization (KASLR) is enabled, and given that this is a feature we
can live without (virtual KASLR is much more important), let's disable
the physical part of KASLR when booting on AMI UEFI firmware claiming to
implement revision v2.0 of the specification (which was released in
2006), as this is the version these systems advertise.

We write 0 to DP_LINK_BW_SET (DPCD 100h) even when using
DP_LINK_RATE_SET (DPCD 114h). Stop doing that, as it can cause the panel
to ignore the rate set method.
Moreover, 0 is a reserved value for DP_LINK_BW_SET, and should not be
used.

plane_view_scanout_stride() currently assumes that we had to pad the
mapping stride with dummy pages in order to align it. But that is not
the case if the original fb stride exceeds the aligned stride used
to populate the remapped view, which is calculated from the user
specified framebuffer width rather than the user specified framebuffer
stride.
Ignore the original fb stride in this case and just stick to the POT
aligned stride. Getting this wrong will cause the plane to fetch the
wrong data, and can lead to fault errors if the page tables at the
bogus location aren't even populated.
TODO: figure out if this is OK for CCS, or if we should instead increase
the width of the view to cover the entire user specified fb stride
instead...

Since the plane_state variable is declared outside the scaler_users
loop in intel_atomic_setup_scalers(), and it's never reset back to
NULL inside the loop we may end up calling intel_atomic_setup_scaler()
with a non-NULL plane state for the pipe scaling case. That is bad
because intel_atomic_setup_scaler() determines whether we are doing
plane scaling or pipe scaling based on plane_state!=NULL. The end
result is that we may miscalculate the scaler mode for pipe scaling.
The hardware becomes somewhat upset if we end up in this situation
when scanning out a planar format on a SDR plane. We end up
programming the pipe scaler into planar mode as well, and the
result is a screenfull of garbage.
Fix the situation by making sure we pass the correct plane_state==NULL
when calculating the scaler mode for pipe scaling.

On ADL+ the hardware automagically calculates the CCS AUX surface
stride from the main surface stride, so when remapping we can't
really play a lot of tricks with the main surface stride, or else
the AUX surface stride would get miscalculated and no longer
match the actual data layout in memory.
Supposedly we could remap in 256 main surface tile units
(AUX page(4096)/cachline(64)*4(4x1 main surface tiles per
AUX cacheline)=256 main surface tiles), but the extra complexity
is probably not worth the hassle.
So let's just make sure our mapping stride is calculated from
the full framebuffer stride (instead of the framebuffer width).
This way the stride we program into PLANE_STRIDE will be the
original framebuffer stride, and thus there will be no change
to the AUX stride/layout.

Commit 503579448d ("drm/i915/gsc: Mark internal GSC engine with reserved uabi class")
made the GSC0 engine not have a valid uabi class and so broke the engine
reset counting, which in turn was made class based in cb823ed991 ("drm/i915/gt: Use intel_gt as the primary object for handling resets").
Despite the title and commit text of the latter is not mentioning it (and
has left the storage array incorrectly sized), tracking by class, despite
it adding aliasing in hypthotetical multi-tile systems, is handy for
virtual engines which for instance do not have a valid engine->id.
Therefore we keep that but just change it to use the internal class which
is always valid. We also add a helper to increment the count, which
aligns with the existing getter.
What was broken without this fix were out of bounds reads every time a
reset would happen on the GSC0 engine, or during selftests when storing
and cross-checking the counts in igt_live_test_begin and
igt_live_test_end.

The rvu_dl will be freed in rvu_nix_health_reporters_destroy(rvu_dl)
after the create_workqueue fails, and after that free, the rvu_dl will
be translate back through the following call chain:
rvu_nix_health_reporters_destroy
|-> rvu_nix_health_reporters_create
|-> rvu_health_reporters_create
|-> rvu_register_dl (label err_dl_health)
Finally. in the err_dl_health label, rvu_dl being freed again in
rvu_health_reporters_destroy(rvu) by rvu_nix_health_reporters_destroy.
In the second calls of rvu_nix_health_reporters_destroy, however,
it uses rvu_dl->rvu_nix_health_reporter, which is already freed at
the end of rvu_nix_health_reporters_destroy in the first call.
So this patch prevents the first destroy by instantly returning -ENONMEN
when create_workqueue fails. In addition, since the failure of
create_workqueue is the only entrence of label err, it has been
integrated into the error-handling path of create_workqueue.

The old implementation extracted VLAN TCI info from the payload
before the VLAN tag has been pushed in the payload.
Another problem was that the VLAN TCI was extracted even if the
packet did not have VLAN protocol header.
This resulted in invalid VLAN TCI and as a consequence a random
queue was computed.
This patch fixes the above issues and use the VLAN TCI from the
skb if it is present or VLAN TCI from payload if present. If no
VLAN header is present queue 0 is selected.

Otherwise, the SPI hardware will transmit/receive one word per DMA

File reference cycles have caused lots of problems for io_uring
in the past, and it still doesn't work exactly right and races with
unix_stream_read_generic(). The safest fix would be to completely
disallow sending io_uring files via sockets via SCM_RIGHT, so there
are no possible cycles invloving registered files and thus rendering
SCM accounting on the io_uring side unnecessary.
