Merge git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-for-linus
* 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
