Subject[PATCH v8 00/19] virtio: alignment issues


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?
