Pull x86 resource control updates from Borislav Petkov:

 - Add support for AMD's Smart Data Cache Injection feature which allows
   for direct insertion of data from I/O devices into the L3 cache, thus
   bypassing DRAM and saving its bandwidth; the resctrl side of the
   feature allows the size of the L3 used for data injection to be
   controlled

 - Add Intel Clearwater Forest to the list of CPUs which support
   Sub-NUMA clustering

 - Other fixes and cleanups
