Yes, set_memory_ro/set_memory_rw were implemented for ARM
(75374ad47 ARM: mm: Define set_memory_* functions for ARM) and should
be in v3.14. Note that these are restricted to module addresses only
since changing individual pages of generic memory is not possible
due to the section mappings used in lowmem.

Thanks,
