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.
