arm64: text replication: add test module
Add a module to allow kernel text replication to be tested; this exposes some data in procfs which can be used to verify that: (a) we're using different page tables in TTBR1 on CPUs in different NUMA nodes (b) that CPUs in different NUMA nodes are indeed accessing different copies of the kernel Signed-off-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk>
