  x86/resctrl: Support wider MBM counters (2020-05-06 18:08:32 +0200)

----------------------------------------------------------------
Add support for wider Memory Bandwidth Monitoring counters by querying
their width from CPUID. As a prerequsite, streamline and unify the CPUID
detection of the respective resource control attributes. By Reinette
Chatre.

----------------------------------------------------------------
Reinette Chatre (7):
      x86/resctrl: Rename asm/resctrl_sched.h to asm/resctrl.h
      x86/cpu: Move resctrl CPUID code to resctrl/
      x86/resctrl: Remove unnecessary RMID checks
      x86/resctrl: Query LLC monitoring properties once during boot
      x86/resctrl: Maintain MBM counter width per resource
      x86/resctrl: Support CPUID enumeration of MBM counter width
      x86/resctrl: Support wider MBM counters
