[GIT PULL] paravirt_ops and xen updates for 2.6.24

[Jeremy Fitzhardinge <jeremy@goop.org>]

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
