drm/amdgpu: Reset the clear flag in buddy during resume
- Added a handler in DRM buddy manager to reset the cleared
flag for the blocks in the freelist.
- This is necessary because, upon resuming, the VRAM becomes
cluttered with BIOS data, yet the VRAM backend manager
believes that everything has been cleared.
v2:
- Add lock before accessing drm_buddy_clear_reset_blocks()(Matthew Auld)
- Force merge the two dirty blocks.(Matthew Auld)
- Add a new unit test case for this issue.(Matthew Auld)
- Having this function being able to flip the state either way would be
good. (Matthew Brost)
v3(Matthew Auld):
- Do merge step first to avoid the use of extra reset flag.
