Bugzilla: https://bugzilla.redhat.com/2160210 commit ef6458b1b6ca3fdb991ce4182e981a88d4c58c0f Author: Peter Collingbourne <pcc@google.com> Date: Thu Nov 3 18:10:37 2022 -0700 mm: Add PG_arch_3 page flag As with PG_arch_2, this flag is only allowed on 64-bit architectures due to the shortage of bits available. It will be used by the arm64 MTE code in subsequent patches.
