<div class='commit-subject'>Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost</div><div class='commit-msg'>Pull virtio updates from Michael Tsirkin:
 "virtio, vhost: new device, fixes, speedups

  This includes the new virtio crypto device, and fixes all over the
  place. In particular enabling endian-ness checks for sparse builds
  found some bugs which this fixes. And it appears that everyone is in
  agreement that disabling endian-ness sparse checks shouldn't be
  necessary any longer.

  So this enables them for everyone, and drops the __CHECK_ENDIAN__ and
  __bitwise__ APIs.

  IRQ handling in virtio has been refactored somewhat, the larger switch
  to IRQ_SHARED will have to wait as it proved too aggressive"
