Subject: [RFC PATCH 0/3] x86/mm: LAM fixups and cleanups

This series has a few fixups and cleanups for LAM code noticed through
code inspection. They are marked as RFC because I am not very familiar
with this code so I may have gotten something (or all of it) wrong.

Yosry Ahmed (3):
  x86/mm: fix LAM cr3 mask inconsistency during context switch
  x86/mm: make sure LAM is up-to-date during context switching
  x86/mm: cleanup prctl_enable_tagged_addr() nr_bits error checking
