https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217138 --- Comment #40 from commit-hook@freebsd.org --- A commit references this bug: Author: kib Date: Mon Apr 10 15:32:26 UTC 2017 New revision: 316679 URL: https://svnweb.freebsd.org/changeset/base/316679 Log: Do not lose dirty bits for removing PROT_WRITE on arm64. Arm64 pmap interprets accessed writable ptes as modified, since ARMv8.0 does not track Dirty Bit Modifier in hardware. If writable bit is removed, page must be marked as dirty for MI VM. This change is most important for COW, where fork caused losing content of the dirty pages which were not yet scanned by pagedaemon.
