Hi Andi,

This series of patches implements the Xen paravirt-ops interface.
It applies to 2.6.21-git3 + ff patches-2.6.21-git3-070501-1.tar.gz.

Changes since the last posting:
- reviews of xenbus (me), netfront (hch, rusty, herbert xu) and
blockfront (hch), with most comments addressed. Netfront review
revealed a couple of real bugs, and the code for all three is looking
cleaner overall.
- Folded bugfix patches into their main patch
- Lots of little style and other cleanups

There may be a trivial conflict in xen-hvc-console because of the
lguest console.

These patches are now moderately well tested, with several successful
runs through XenSource's regression test suite, and some amount of
non-me testing. While I wouldn't go into production with a
xen/paravirt_ops kernel right now, it does seem pretty functional.

This series generally restricts itself to Xen-specific parts of the
tree, though it does make a few small changes elsewhere.

It includes:
- some helper routines for allocating address space and walking pagetables
- Xen interface header files
- Core Xen implementation
- Efficient late-pinning/early-unpinning pagetable handling
- Virtualized time, including stolen time
- SMP support
- Preemption support
- Batched pagetable updates
- Xen console, based on hvc console
- Xenbus
- Netfront, the paravirtualized network device
- Blockfront, the paravirtualized block device

Thanks,
J
