Revision 18ebab9dc486b93fd20f4ecdabac1573c078e295 authored by Alan Cox on 28 June 2017, 04:01:29 UTC, committed by Alan Cox on 28 June 2017, 04:01:29 UTC
  Refine the fix from r312954.  Specifically, add a new PDE-only flag,
  PG_PROMOTED, that indicates whether lingering 4KB page mappings might
  need to be flushed on a PDE change that restricts or destroys a 2MB
  page mapping.  This flag allows the pmap to avoid range invalidations
  that are both unnecessary and costly.
