Merge tag 'stable/for-linus-3.4-tag-two' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen
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.
