From: "Russell King (Oracle)" <rmk+kernel@xxxxxxxxxxxxxxx>
Add changes for CNP (Common Not Private) support of kernel text
replication. Although text replication has only been tested on
dual-socket Ampere A1 systems, provided the different NUMA nodes
are not part of the same inner shareable domain, CNP should not
be a problem.
