Merge tag 'stable/for-linus-3.11-rc0-tag-two' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen

Pull Xen bugfixes from Konrad Rzeszutek Wilk:
 - Fix memory leak when CPU hotplugging.
 - Compile bugs with various #ifdefs
 - Fix state changes in Xen PCI front not dealing well with new
   toolstack.
 - Cleanups in code (use pr_*, fix 80 characters splits, etc)
 - Long standing bug in double-reporting the steal time

* tag 'stable/for-linus-3.11-rc0-tag-two' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen:
  xen/time: remove blocked time accounting from xen "clockchip"
  xen: Convert printks to pr_<level>
  xen: ifdef CONFIG_HIBERNATE_CALLBACKS xen_*_suspend
  xen/pcifront: Deal with toolstack missing 'XenbusStateClosing' state.
  xen/time: Free onlined per-cpu data structure if we want to online it again.
  xen/time: Check that the per_cpu data structure has data before freeing.
  xen/time: Don't leak interrupt name when offlining.
  xen/time: Encapsulate the struct clock_event_device in another structure.
  xen/spinlock: Don't leak interrupt name when offlining.
  xen/smp: Don't leak interrupt name when offlining.
  xen/smp: Set the per-cpu IRQ number to a valid default.
  xen/smp: Introduce a common structure to contain the IRQ name and interrupt line.
  xen/smp: Coalesce the free_irq calls in one function.
  xen-pciback: fix error return code in pcistub_irq_handler_switch()
