Merge tag 'virtio-next-for-linus' of git://git./linux/kernel/git/rusty/linux

Pull virtio updates from Rusty Russell:
 "Main excitement is a virtio_scsi fix for alloc holding spinlock on the
  abort path, which I refuse to CC stable since (1) I discovered it
  myself, and (2) it's been there forever with no reports"

* tag 'virtio-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux:
  virtio_scsi: don't call virtqueue_add_sgs(... GFP_NOIO) holding spinlock.
  virtio-rng: fixes for device registration/unregistration
  virtio-rng: fix boot with virtio-rng device
  virtio-rng: support multiple virtio-rng devices
  virtio_ccw: introduce device_lost in virtio_ccw_device
  virtio: virtio_break_device() to mark all virtqueues broken.
