Merge tag 'stable/for-linus-3.9-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen

Pull Xen fixes from Konrad Rzeszutek Wilk:
 - Compile warnings and errors (one on x86, two on ARM)
 - WARNING in xen-pciback
 - Use the acpi_processor_get_performance_info instead of the 'register'
   version

* tag 'stable/for-linus-3.9-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen:
  xen/acpi: remove redundant acpi/acpi_drivers.h include
  xen: arm: mandate EABI and use generic atomic operations.
  acpi: Export the acpi_processor_get_performance_info
  xen/pciback: Don't disable a PCI device that is already disabled.
