[Xen-devel] [RFC PATCH 02/31] pm: move processor_perf.h file to the xen/include/xen location

[Oleksandr Tyshchenko <olekstysh@xxxxxxxxx>]

From: Oleksandr Dmytryshyn <oleksandr.dmytryshyn@xxxxxxxxxxxxxxx>

Cpufreq driver should be more generalizable (not ACPI-specific).
Thus this file should be placed to more convenient location.

This is a rebased version of the original patch:
