Hi,
This is a series to allow CONFIG_DEBUG_SET_MODULE_RONX to be used on ARM. The
current config description from x86 describes it best:
This option helps catch unintended modifications to loadable
kernel module's text and read-only data. It also prevents execution
of module data. Such protection may interfere with run-time code
patching and dynamic kernel tracing - and they might also protect
against certain classes of kernel exploits.
v2: Add module bounds checking per Russell, removed dsb per Catalin.
Macrofied the set_memory_* functions to avoid so much code duplication.
Thanks,
Laura
