Merge tag 'x86_cache_for_6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 cache resource control updates from Dave Hansen:
 "These declare the resource control (rectrl) MSRs a bit more normally
  and clean up an unnecessary structure member:

   - Remove unnecessary arch_has_empty_bitmaps structure memory

   - Move rescrtl MSR defines into msr-index.h, like normal MSRs"

* tag 'x86_cache_for_6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86/resctrl: Move MSR defines into msr-index.h
  x86/resctrl: Remove arch_has_empty_bitmaps
