[PATCH v8 00/19] virtio: alignment issues

[Michael S. Tsirkin]

This is an alternative to
	vhost: force spec specified alignment on types
which is a bit safer as it does not change UAPI.
I still think it's best to change the UAPI header as well,
we can do that as a follow-up cleanup.

changes from v7:
	typo fix
changes from v6:
	add missing header includes all over the place
changes from v5:
	ack for mellanox patch
	fixup to remoteproc
changes from v4:
	fixup to issues reported by kbuild
changes from v3:
	tools/virtio fixes
	a bunch more cleanups that now become possible

Changes from v2:
	don't change struct name, instead add ifndef
	so kernel does not see the legacy UAPI version.

Jason, can you pls ack one of the approaches?
