Merge git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-lguest
* git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-lguest: (45 commits) Use "struct boot_params" in example launcher Loading bzImage directly. Revert lguest magic and use hook in head.S Update lguest documentation to reflect the new virtual block device name. generalize lgread_u32/lgwrite_u32. Example launcher handle guests not being ready for input Update example launcher for virtio Lguest support for Virtio Remove old lguest I/O infrrasructure. Remove old lguest bus and drivers. Virtio helper routines for a descriptor ringbuffer implementation Module autoprobing support for virtio drivers. Virtio console driver Block driver using virtio. Net driver using virtio Virtio interface Boot with virtual == physical to get closer to native Linux. Allow guest to specify syscall vector to use. Rename "cr3" to "gpgdir" to avoid x86-specific naming. Pagetables to use normal kernel types ...
