  x86/mm/tlb: Ignore f->new_tlb_gen when zero (2022-07-19 09:04:52 -0700)

----------------------------------------------------------------
- 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.
