[GIT PULL] (xen) stable/drivers for 3.1

[Konrad Rzeszutek Wilk]

Hey Linus,

Please pull:

git pull git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/drivers

which has patches since git commit 56299378726d5f2ba8d3c8cbbd13cb280ba45e4f
Linus Torvalds (1):
    Linux 3.0-rc4

This pull contains the following components:
 - VGA text support. Since Xen is the first payload on the bootloader it gets the
   screen information - now with this patch we can copy it from the hypervisor
   and enjoy 80x25 old-school text output.
 - MODULE_ALIAS on backends so that udev will autoload them.
 - tmem driver to shuffle file-system and swap pages between guests as appropiate.
   Runtime it is disabled unless 'tmem' parameter is supplied.
 - self balloon driver to decrease memory in the guest and make the swap pages
   be shuffled by tmem to be compressed/shared/etc. Runtime wise it is disabled
   by default (use 'selfballooning' to enable it and make sure you have a swap disk).
 - pciback backend. It complements the xen pci front driver which together
   allow guests to have host's PCI devices.

The credit list and diff stat is as follow:

Bastian Blank (2):
      xen: Populate xenbus device attributes
      xen: Add module alias to autoload backend drivers

Dan Magenheimer (2):
      xen: prepare tmem shim to handle frontswap
      xen: tmem: self-ballooning and frontswap-selfshrinking

Ian Campbell (1):
      xen: rename pciback module to xen-pciback.

Jeremy Fitzhardinge (1):
      xen: allow enable use of VGA console on dom0

Joe Perches (1):
      xen: Add __attribute__((format(printf... where appropriate
