* git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-for-linus:
  lguest: notify on empty
  virtio: force callback on empty.
  virtio_blk: fix endianess annotations
  virtio_config: fix len calculation of config elements
  virtio_net: another race with virtio_net and enable_cb
  virtio: An entropy device, as suggested by hpa.
  virtio_blk: allow read-only disks
  lguest: fix ugly <NULL> in /proc/interrupts
  virtio: set device index in common code.
  virtio: virtio_pci should not set bus_id.
  virtio: bus_id for devices should contain 'virtio'
  Fix crash in virtio_blk during modprobe ; rmmod ; modprobe
  lguest: use ioremap_cache, not ioremap
