Merge tag 'stable/for-linus-3.10-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen

Pull Xen fixes from Konrad Rzeszutek Wilk:
 - Use proper error paths
 - Clean up APIC IPI usage (incorrect arguments)
 - Delay XenBus frontend resume is backend (xenstored) is not running
 - Fix build error with various combinations of CONFIG_

  xenbus_client.c: correct exit path for xenbus_map_ring_valloc_hvm
  xen-pciback: more uses of cached MSI-X capability offset
  xen: Clean up apic ipi interface
  xenbus: save xenstore local status for later use
  xenbus: delay xenbus frontend resume if xenstored is not running
  xmem/tmem: fix 'undefined variable' build error.
