Subject: [GIT PULL] (xen) stable/for-linus-fixes-3.3 bug-fix for rc1.

Hey Linus,

Please pull this branch, which has one fix:

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/for-linus-fixes-3.3

which is a fix to Kay Sievers global "convert sysdev_class -> device/subsystem" patchset
which inadvertly missed the proper subsystem in the balloon code. The negative effect
of his patch is that the xen tool stack can't now properly balloon the memory hence
we can't launch the guests.
  
The patch is based on 070680218379e15c1901f4bf21b98e3cbf12b527, which
was the "xen-balloon: convert sysdev_class to a regular subsystem"

Konrad Rzeszutek Wilk (1):
      xen/balloon: Move the registration from device to subsystem.
