[Intel-gfx] [PATCH 0/9] shmem helper untangling

[Daniel Vetter]

Hi all,

I've started this a while ago, with the idea to move shmem helpers over
to dma_resv_lock. Big prep work for that was to untangle the layering
between functions called by drivers, and functions used to implement
drm_gem_object_funcs.

I didn't ever get to the locking part, but I think the cleanup here are
worth it stand-alone still.

Comments, review and testing very much welcome.

Cheers, Daniel
