[PATCH v4 0/6] drm/xe: Make struct xe_ggtt private.

[Maarten Lankhorst <dev@lankhorst.se>]

SRIOV-VF node shifting code uses a complicated system with balloons
to limit allocation and size. Since size never changes after init,
shifting can simply be done by taking the the GGTT lock and then
moving each offset.

First introduce a function to shift an entire GGTT, this removes the
need for the balloons, then also perform the display code pinning
through a callback, and finally privatize the struct.

No other users outside of xe_ggtt remain, and we can make xe_ggtt private.

Rebased, no functional changes since v3.

Maarten Lankhorst (5):
  drm/xe: Only have a single drmm release action.
  drm/xe: Start using ggtt->start in preparation of balloon removal
  drm/xe: Rewrite GGTT VF initialisation
  drm/xe: Convert xe_fb_pin to use a callback for insertion into GGTT
  drm/xe: Move struct xe_ggtt to xe_ggtt.c

Tomasz Lis (1):
  drm/mm: Introduce address space shifting
