Merge branch 'x86-cache-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 cache control updates from Borislav Petkov:

 - The generalization of the RDT code to accommodate the addition of
   AMD's very similar implementation of the cache monitoring feature.

   This entails a subsystem move into a separate and generic
   arch/x86/kernel/cpu/resctrl/ directory along with adding
   vendor-specific initialization and feature detection helpers.

   Ontop of that is the unification of user-visible strings, both in the
   resctrl filesystem error handling and Kconfig.

   Provided by Babu Moger and Sherry Hurwitz.

 - Code simplifications and error handling improvements by Reinette
   Chatre.
