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

Pull x86 cache resource controller updates from Thomas Gleixner:
 "An update for the Intel Resource Director Technolgy (RDT) which adds a
  feedback driven software controller to runtime adjust the bandwidth
  allocation MSRs.

  This makes the allocations more accurate and allows to use bandwidth
  values in understandable units (MB/s) instead of using percentage
  based allocations as the original, still available, interface.

  The software controller can be enabled with a new mount option for the
  resctrl filesystem"
