[PATCH v4 0/3] drm/xe/vf: Post-migration recovery of GGTT nodes and CTB

[Tomasz Lis <tomasz.lis@intel.com>]

To support VF Migration, it is necessary to do fixups to any
non-virtualized resources. These fixups need to be applied within
VM, on the KMD working with VF.

This series adds two fixup functions to the recovery worker:
* for fixing drm_mm nodes which represent GGTT allocations
* for fixing content of outgoing CTB buffer

v2: Fixed missing include, made checkpatch happy
v3: Moved some functs to xe_ggtt.c; moved shift computation to just
  after querying; improved documentation; switched some warns to asserts;
  skipping fixups when GGTT shift eq 0; iterating through tiles rather
  than gts; fixes in log messages
v4: Updated kerneldocs, removed unused funct, properly allocate
  balloning nodes if non existent, removed inline keywords, enums for
  offsets in CTB messages, less error messages, if return unused then
  made functs void

Tomasz Lis (3):
  drm/drm_mm: Safe macro for iterating through nodes in range
  drm/xe/sriov: Shifting GGTT area post migration
  drm/xe/vf: Fixup CTB send buffer messages after migration
