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. Approved by: re (kib)
