Hi Linus,

Please pull:

ssh://master.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git xen-upstream

This contains updates for arch/x86 paravirt_ops and Xen.

A quick overview of the patchset:

paravirt_ops:
Remove the monolithic paravirt_ops structure, and replace it with
smaller structures of related functions. Also, clean up the handling
of lazy mode to make it easier to implement.

x86/mm/init.c: remove a chunk of dead code

Xen:
- remove duplicate includes
- yield if the target vcpu of an IPI is not currently running
- add post-batch callbacks for multicalls [*]
- deal with unpinning pagetables when another vcpu still
has a cr3 reference [*]
- deal with split ptelocks by pinning each pte page
separately under lock
- determine the kernel/hypervisor address split dynamically
- use the right arg structure for register_vcpu_info [*]
- add extra debugging output for failed multicalls

XFS:
- eagerly unmap vmapped areas to avoid confict with Xen [*]

[*] bugfix needed for 2.6.23. I've also cc:d them to stable@kernel.org
