This is recommended by HW designers. Previously when it was set to 1,
the PDE walk error in VM fault will be treated as
PERMISSION_OR_INVALID_PAGE_FAULT rather than usually expected OTHER_FAULT.
As a result, the retry control in VM_CONTEXT*_CNTL will change accordingly.

The above behavior is kind of abnormal. Furthermore, the
PDE_FAULT_CLASSIFICATION == 1 feature was targeted for very old ASICs
and it never made it way to production. Therefore, we should set it to 0.

Use HMM helper function hmm_vma_fault() to get physical pages backing
userptr and start CPU page table update track of those pages. Then use
hmm_vma_range_done() to check if those pages are updated before
amdgpu_cs_submit for gfx or before user queues are resumed for kfd.

If userptr pages are updated, for gfx, amdgpu_cs_ioctl will restart
from scratch, for kfd, restore worker is rescheduled to retry.

HMM simplify the CPU page table concurrent update check, so remove
guptasklock, mmu_invalidations, last_set_pages fields from
amdgpu_ttm_tt struct.

HMM does not pin the page (increase page ref count), so remove related
operations like release_pages(), put_page(), mark_page_dirty().

[Why]
dc_commit_updates_for_stream is called twice per stream: once
with the flip data and once will all other data. This causes
problems when these DC calls have different numbers of planes

For example, a commit with a pageflip on plane A and a
non-pageflip change on plane B will first call
into DC with just plane A, causing plane B to be
disabled. Then it will call into DC with both planes,
re-enabling plane B

[How]
Merge flip and full into a single bundle

Apart from the single DC call, the logic should not be
changed by this patch

[Why]
eDP v1.4 allows panels to report link rates other than RBR/HBR/HBR2, that
may be more optimal for the panel's timing. Power can be saved by using
a link rate closer to the required bandwidth of the panel's timing.

[How]
Scan the table of reported link rates from the panel, and select the
minimum link rate that satisfies the bandwidth requirements of the panel's
timing. Include a flag to make the feature optional.
