[RESEND] [PATCH v6 0/8] do not store GPU address in TTM

[Nirmoy Das <nirmoy.aiemd@gmail.com>]

With this patch series I am trying to remove GPU address dependency in
TTM and moving GPU address calculation to individual drm drivers. This
cleanup will simplify introduction of drm_mem_region/domain work started
by Brian Welty[1].


It would be nice if someone test this for nouveau. Rest of the drivers
are already tested.

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

v4:
* minor coding style fixes in amdgpu and radeon
* remove unnecessary kerneldoc for internal function

v5:
* rebase on top of drm-misc-next
* fix return value of drm_gem_vram_pg_offset()
* add a comment in drm_gem_vram_pg_offset() to clearify why we return 0.

v6:
* rebase to drm-misc-next
* removed acked for vmwgfx as there was a small conflict

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 v3
  drm/qxl: don't use ttm bo->offset
  drm/vram-helper: don't use ttm bo->offset v4
  drm/bochs: use drm_gem_vram_offset to get bo offset v2
  drm/ttm: do not keep GPU dependent addresses
