Fixes for v6.12

Display:
- move CRTC resource assignment to atomic_check otherwise to make
  consecutive calls to atomic_check() consistent
- fix rounding / sign-extension issues with pclk calculation in
  case of DSC
- cleanups to drop incorrect null checks in dpu snapshots
- fix to use kvzalloc in dpu snapshot to avoid allocation issues
  in heavily loaded system cases
- Fix to not program merge_3d block if dual LM is not being used
- Fix to not flush merge_3d block if its not enabled otherwise
  this leads to false timeouts

- a7xx: add a fence wait before SMMU table update
Signed-off-by: Dave Airlie <airlied@redhat.com>
From: Rob Clark <robdclark@gmail.com>

The CP_SMMU_TABLE_UPDATE _should_ be waiting for idle, but on some
devices (x1-85, possibly others), it seems to pass that barrier while
there are still things in the event completion FIFO waiting to be
written back to memory.

Work around that by adding a fence wait before context switch.  The
CP_EVENT_WRITE that writes the fence is the last write from a submit,
so seeing this value hit memory is a reliable indication that it is
safe to proceed with the context switch.

v2: Only emit CP_WAIT_TIMESTAMP on a7xx, as it is not supported on a6xx.
    Conversely, I've not been able to reproduce this issue on a6xx, so
    hopefully it is limited to a7xx, or perhaps just certain a7xx
    devices.

Don't set the merge_3d pending flush bits if the mode_3d is
BLEND_3D_NONE.

Always flushing merge_3d can cause timeout issues when there are
multiple commits with concurrent writeback enabled.

This is because the video phys enc waits for the hw_ctl flush register
to be completely cleared [1] in its wait_for_commit_done(), but the WB
encoder always sets the merge_3d pending flush during each commit
regardless of if the merge_3d is actually active.

This means that the hw_ctl flush register will never be 0 when there are
multiple CWB commits and the video phys enc will hit vblank timeout
errors after the first CWB commit.

With the "drm/msm: add a display mmu fault handler" series [1] we saw
issues in the field where memory allocation was failing when
allocating space for registers in msm_disp_state_dump_regs().
Specifically we were seeing an order 5 allocation fail. It's not
surprising that order 5 allocations will sometimes fail after the
system has been up and running for a while.

There's no need here for contiguous memory. Change the allocation to
kvzalloc() which should make it much less likely to fail.

If the allocation in msm_disp_state_dump_regs() failed then
`block->state` can be NULL. The msm_disp_state_print_regs() function
_does_ have code to try to handle it with:

  if (*reg)
    dump_addr = *reg;

...but since "dump_addr" is initialized to NULL the above is actually
a noop. The code then goes on to dereference `dump_addr`.

Make the function print "Registers not stored" when it sees a NULL to
solve this. Since we're touching the code, fix
msm_disp_state_print_regs() not to pointlessly take a double-pointer
and properly mark the pointer as `const`.

When (mode->clock * 1000) is larger than (1<<31), int to unsigned long
conversion will sign extend the int to 64 bits and the pclk_rate value
will be incorrect.

Fix this by making the result of the multiplication unsigned.

Note that above (1<<32) would still be broken and require more changes, but
its unlikely anyone will need that anytime soon.

Historically CRTC resources (LMs and CTLs) were assigned in
dpu_crtc_atomic_begin(). The commit 9222cdd2 ("drm/msm/dpu: move hw
resource tracking to crtc state") simply moved resources to
struct dpu_crtc_state, without changing the code sequence. Later on the
commit b107603b ("drm/msm/dpu: map mixer/ctl hw blocks in encoder
modeset") rearanged the code, but still kept the cstate->num_mixers
assignment to happen during commit phase. This makes dpu_crtc_state
inconsistent between consequent atomic_check() calls.

Move CRTC resource assignment to happen at the end of
dpu_encoder_virt_atomic_check().

Commit ac9f97ff ("powerpc/8xx: Inconditionally use task PGDIR in
DTLB misses") relies on re-reading DAR register to know if an error is
due to a missing copy of a PMD entry in task's PGDIR, allthough DAR
was already read in the exception prolog and copied into thread
struct. This is because is it done very early in the exception and
there are not enough registers available to keep a pointer to thread
struct.

However, dcbz instruction is buggy and doesn't update DAR register on
fault. That is detected and generates a call to FixupDAR workaround
which updates DAR copy in thread struct but doesn't fix DAR register.

Let's fix DAR in addition to the update of DAR copy in thread struct.
