x86/intel_rdt: Support creation/removal of pseudo-locked region
The user triggers the creation of a pseudo-locked region when writing a valid schemata to the schemata file of a resource group in the pseudo-locksetup mode. A valid schemata is one that: (1) does not overlap with any other resource group, (2) does not involve a cache that already contains a pseudo-locked region within its hierarchy. After a valid schemata is parsed the system is programmed to associate the to be pseudo-lock bitmask with the closid associated with the resource group. With the system set up the pseudo-locked region can be created. Signed-off-by:Reinette Chatre <reinette.chatre@intel.com> Signed-off-by:
