[PATCH v3 0/8] do not store GPU address in TTM

[Nirmoy Das]

With this patch series I am trying to remove GPU address dependency in
TTM and moving GPU address calculation to individual drm drivers.

I tested this patch series on qxl, bochs and amdgpu. Christian tested it on radeon HW.
It would be nice if someone test this for nouveau and vmgfx.

v2:
* set bo->offset = 0 for drm/nouveau if bo->mem.mm_node == NULL

v3:
* catch return value of drm_gem_vram_offset() in drm/bochs
* introduce drm_gem_vram_pg_offset() in vram helper
* improve nbo->offset calculation for nouveau

Nirmoy Das (8):
  drm/amdgpu: move ttm bo->offset to amdgpu_bo
  drm/radeon: don't use ttm bo->offset
  drm/vmwgfx: don't use ttm bo->offset
  drm/nouveau: don't use ttm bo->offset
  drm/qxl: don't use ttm bo->offset
  drm/vram-helper: don't use ttm bo->offset
  drm/bochs: use drm_gem_vram_offset to get bo offset
  drm/ttm: do not keep GPU dependent addresses
