* git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-for-linus:
  lguest: struct device - replace bus_id with dev_name()
  lguest: move the initial guest page table creation code to the host
  kvm-s390: implement config_changed for virtio on s390
  virtio_console: support console resizing
  virtio: add PCI device release() function
  virtio_blk: fix type warning
  virtio: block: dynamic maximum segments
  virtio: set max_segment_size and max_sectors to infinite.
  virtio: avoid implicit use of Linux page size in balloon interface
  virtio: hand virtio ring alignment as argument to vring_new_virtqueue
  virtio: use KVM_S390_VIRTIO_RING_ALIGN instead of relying on pagesize
  virtio: use LGUEST_VRING_ALIGN instead of relying on pagesize
  virtio: Don't use PAGE_SIZE for vring alignment in virtio_pci.
  virtio: rename 'pagesize' arg to vring_init/vring_size
  virtio: Don't use PAGE_SIZE in virtio_pci.c
  virtio: struct device - replace bus_id with dev_name(), dev_set_name()
  virtio-pci queue allocation not page-aligned
