Subject: [PATCH v3 0/2] virtio: feature related cleanups

Cleanup around handling of feature bits:
- address word/dword/qword confusion
- simplify interfaces so callers do not need to
  remember in which 64 bit chunk each bit belongs

changes from v2:
- drop unnecessary casts
- rework the interface to use array of bits not
  arrays of qwords

Michael S. Tsirkin (2):
  virtio: clean up features qword/dword terms
  vhost: switch to arrays of feature bits
