Merge tag 'x86_cache_updates_for_5.8' of git://git.kernel.org/pub/scm/linux/kernel...

Pull x86 cache resource control updates from Borislav Petkov:
 "Add support for wider Memory Bandwidth Monitoring counters by querying
  their width from CPUID.

  As a prerequsite for that, streamline and unify the CPUID detection of
  the respective resource control attributes.

  By Reinette Chatre"
