The first patch addresses performance regression introduced by XSA-336 fixes.
This patch could be considered as a candidate for inclusion in 4.15.

The second patch is a minor cleanup and can safely wait until after 4.15.

  x86/vpt: Do not take pt_migrate rwlock in some cases
  x86/vpt: Simplify locking argument to write_{un}lock

Thank you, but I think this is too late for 4.15.
