- drm/nouveau/bios: make const arrays hwsq_signature and edid_sig static · 1a5c8164
  Colin Ian King authored Nov 02, 2017
```
Don't populate arrays hwsq_signature and edid_sig on the stack but
instead make them static. Makes the object code smaller by over 190
bytes:

  35676    3312      64   39052    988c nouveau_bios.o

After:

- drm/nouveau: queue delayed unmapping of VMAs on client workqueue · 00d041d0
  Ben Skeggs authored Nov 01, 2017
```
VMAs are about to not take references on the VMM they belong to, which
means more care is required when handling delayed unmapping.

Queuing it on the client workqueue ensures all pending VMA unmaps will
have completed before the VMM is destroyed.

- drm/nouveau: check kind validity against mmu object · a220dd73
  Ben Skeggs authored Nov 01, 2017
```
This is already handled in the top-level gem_new() ioctl in another manner,
but this will be removed in a future commit.

Ideally we'd not need to check up-front at all, and let the VMM code handle
error checking, but there are paths in the current BO management code where
this isn't possible due to map() not always being called during BO creation,
and map() calls not being allowed to fail during buffer migration.
