commit 20a5f5a98e1bb3d40acd97e89299e8c2d22784be upstream.

Starting with Vega the hardware supports concurrent flushes
of VMID which can be used to implement per process VMID
allocation.

But concurrent flushes are mutual exclusive with back to
back VMID allocations, fix this to avoid a VMID used in
two ways at the same time.

v2: don't set ring to NULL

<title>drm, iommu: Change type of pasid to u32</title>

<content type='text'>
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.

The KFD VMID assignment was hard-coded in a few places. Consolidate that in
a single variable adev-&gt;vm_manager.first_kfd_vmid. The value is still
assigned in gmc-ip-version-specific code.

drm-misc-next for 5.4:

UAPI Changes:

Cross-subsystem Changes:

Core Changes:
  - dma-buf: add reservation_object_fences helper, relax
             reservation_object_add_shared_fence, remove
             reservation_object seq number (and then
             restored)
  - dma-fence: Shrinkage of the dma_fence structure,
               Merge dma_fence_signal and dma_fence_signal_locked,
               Store the timestamp in struct dma_fence in a union with
               cb_list

Driver Changes:
  - More dt-bindings YAML conversions
  - More removal of drmP.h includes
  - dw-hdmi: Support get_eld and various i2s improvements
  - gm12u320: Few fixes
  - meson: Global cleanup
  - panfrost: Few refactors, Support for GPU heap allocations
  - sun4i: Support for DDC enable GPIO
  - New panels: TI nspire, NEC NL8048HL11, LG Philips LB035Q02,
                Sharp LS037V7DW01, Sony ACX565AKM, Toppoly TD028TTEC1
