Merge tag 'x86_mm_for_v6.0_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 mm updates from Borislav Petkov:

 - Rename a PKRU macro to make more sense when reading the code

 - Update pkeys documentation

 - Avoid reading contended mm's TLB generation var if not absolutely
   necessary along with fixing a case where arch_tlbbatch_flush()
   doesn't adhere to the generation scheme and thus violates the
   conditions for the above avoidance.
