Pull resource control updates from Borislav Petkov:

 - Rework different aspects of the resctrl code like adding
   arch-specific accessors and splitting the locking, in order to
   accomodate ARM's MPAM implementation of hw resource control and be
   able to use the same filesystem control interface like on x86. Work
   by James Morse

 - Improve the memory bandwidth throttling heuristic to handle workloads
   with not too regular load levels which end up penalized unnecessarily

 - Use CPUID to detect the memory bandwidth enforcement limit on AMD

 - The usual set of fixes
