[IA64] Add ACPI based P-state support
Patch to support P-state transitions on ia64. This driver is based on ACPI, and uses the ACPI processor driver interface to find out the P-state support information for the processor. This driver plugs into generic cpufreq infrastructure. Once this driver is loaded successfully, ondemand/userspace governor can be used to change the CPU frequency dynamically based on load or on request from userspace process. Refer : ACPI specification - http://www.acpi.info P-state related PAL calls - http://developer.intel.com/design/itanium/downloads/24869909.pdf Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
