[PATCH 0/5] drm/xe: xe-only patches from the multi-device GPUSVM series

[Thomas Hellström]

A collection of misc patches that are prerequisites for the multi-device GPUSVM
series but that are xe-only and can be merged separately.

Patch 1
- Improved conditional compilation for the Xe GPUSVM support
Patch 2
- Fix a pontential UAF
Patch 3
- Adds a bo remove callback. In addition to GPUSVM this will improve
  on our device unbind support.
Patch 4
- A small fix for multi-gpu-svm support
Patch 5
- A change in implicit UAPI and needed for multi-gpu-svm support.

Thomas Hellström (5):
  drm/xe: Introduce CONFIG_DRM_XE_GPUSVM
  drm/xe/svm: Fix a potential bo UAF
  drm/xe/bo: Add a bo remove callback
  drm/xe/migrate: Allow xe_migrate_vram() also on non-pagefault capable
    devices
  drm/xe/uapi, drm/xe: Make the PT code handle placement per PTE rather
    than per vma / range
