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.
