Pull drm updates from Dave Airlie:
 "Not a major amount of change, the i915 trees got split into display
  and gt trees to better facilitate higher level review, and there's a
  major refactoring of i915 GEM locking to use more core kernel concepts
  (like ww-mutexes). msm gets per-process pagetables, older AMD SI cards
  get DC support, nouveau got a bump in displayport support with common
  code extraction from i915.

  Outside of drm this contains a couple of patches for hexint
  moduleparams which you've acked, and a virtio common code tree that
  you should also get via it's regular path.

Allow user to know how many compute units (CU) are in use at any given

[How]

PASID is defined as a few different types in iommu including "int",
"u32", and "unsigned int". To be consistent and to match with uapi
definitions, define PASID and its variations (e.g. max PASID) as "u32".
"u32" is also shorter and a little more explicit than "unsigned int".

No PASID type change in uapi although it defines PASID as __u64 in
some places.

ALLOC_MEM_FLAGS_* used are the same as the KFD_IOC_ALLOC_MEM_FLAGS_*,
but they are interweavedly used in kernel driver, resulting in bad
readability. For example, KFD_IOC_ALLOC_MEM_FLAGS_COHERENT is not
referenced in kernel, and it functions implicitly in kernel through
ALLOC_MEM_FLAGS_COHERENT, causing unnecessary confusion.

Replace all occurrences of ALLOC_MEM_FLAGS_* with
KFD_IOC_ALLOC_MEM_FLAGS_* to solve the problem.

There is an issue that CP will check the HIQ queue to be configured and mapped
with KIQ ring, otherwise, it will be unable to read back the secure buffer while
the gfxoff is enabled even with trusted IP blocks.

v1 -&gt; v2:
- Fix to remove surplus set_resources packets.
- Fill the whole configuration in MQD.
- Change the author as Aaron because he addressed the key point of this issue.
- Add kiq ring lock.

v2 -&gt; v3:
- Free the lock while in error return case.
- Remove the programming only needed by the queue is unmapped.

v3 -&gt; v4:
- Remove doorbell programming because it's used for restarting queue.
- Remove CP scheduler programming because map_queue packet will handle this.

v4 -&gt; v5:
- Remove cp_hqd_active because mec ucode will enable it while use map_queues.
- Revise goto out_unlock.
- Correct the right doorbell offset for HIQ that kfd driver assigned in the
  packet.

v5 -&gt; v6:
- Merge Arcturus fix into this patch because it will get oops in Arcturus
  platform.
