[GIT PULL] Xen updates

[Jeremy Fitzhardinge <jeremy@goop.org>]

 Hi Linus,

Here's a series of Xen core changes for 2.6.37.  I pre-merged with your
tree mainly this codes adds a call to reserve_early(), which needed to
be updated to the memblock equivalent.  I've also given you the
reference to the unmerged branches.

Unmerged branches:
  git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git upstream/core
  git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git upstream/xenfs


Thanks,
	J
