Hey Linus,

Please git pull the following git branch:

git pull git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen stable/vmalloc-3.2

wherein:
#stable/vmalloc-3.2 is based on git commit a102a9ece5489e1718cd7543aa079082450ac3a2
(Linux 3.1-rc8): and it does three major things:
 a). make the backend driver use the API provided by xenbus module instead of its
     own handling (which was duplicated across backends),
 b). removes dead code (ia64),
 c). lays out the groundwork for removing the 'vmalloc_sync_all' patch
     that was added in v3.1 as a bug-fix.

Note: The patches touch other maintainers trees and I've gotten
Acks from them to do this as one patchset instead of cutting it in
small pieces and parceling out.

Note2: The git history is a bit fresh (4 days old) in the branch b/c
I've edited the git commits to add axboe and davem's Ack-by.

David Vrabel (3):
      xen: use generic functions instead of xen_{alloc, free}_vm_area()
      block: xen-blkback: use API provided by xenbus module to map rings
      net: xen-netback: use API provided by xenbus module to map rings
