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.
Nirmoy Das (7):
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/bochs: don't use ttm bo->offset
drm/ttm: do not keep GPU dependent addresses

GPU address should belong to driver not in memory management.
This patch moves ttm bo.offset and gpu_offset calculation to amdgpu driver.

This patch also removes slot->gpu_offset which is not required as
VRAM and PRIV slot are in separate PCI bar
