Subject: [PATCH v2 0/2] virtio/vhost: fix alignment requirements

vhost incorrectly asked for 8 byte alignment for
used ring pointer, it should be 4 byte.

Let's add explicit macros for ring element alignment,
this makes it easier to make sure our requirements
match the spec.

Rusty, OK to merge this through my vhost tree, or do you
prefer merging this through yours?

Michael S. Tsirkin (2):
  virtio_ring: document alignment requirements
  vhost: relax used address alignment
