Pull more xen updates from Konrad Rzeszutek Wilk:
 "One tiny feature that accidentally got lost in the initial git pull:
   * Add fast-EOI acking of interrupts (clear a bit instead of
     hypercall)
  And bug-fixes:
   * Fix CPU bring-up code missing a call to notify other subsystems.
   * Fix reading /sys/hypervisor even if PVonHVM drivers are not loaded.
   * In Xen ACPI processor driver: remove too verbose WARN messages, fix
     up the Kconfig dependency to be a module by default, and add
     dependency on CPU_FREQ.
   * Disable CPU frequency drivers from loading when booting under Xen
     (as we want the Xen ACPI processor to be used instead).
   * Cleanups in tmem code."

* tag 'stable/for-linus-3.4-tag-two' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen:
  xen/acpi: Fix Kconfig dependency on CPU_FREQ
  xen: initialize platform-pci even if xen_emul_unplug=never
  xen/smp: Fix bringup bug in AP code.
  xen/acpi: Remove the WARN's as they just create noise.
  xen/tmem: cleanup
  xen: support pirq_eoi_map
  xen/acpi-processor: Do not depend on CPU frequency scaling drivers.
  xen/cpufreq: Disable the cpu frequency scaling drivers from loading.
  provide disable_cpufreq() function to disable the API.
