Hi,

This is v3 of my series to rename/refactor CONFIG_DEBUG_RODATA
and CONFIG_DEBUG_SET_MODULE_RONX. Among other objections, there shouldn't
be 'debug' in the name since these provide necessary kernel protection.

v3 mostly focuses on changing how the Kconfig dependencies work for the
refactor. Russell King requested that these options be deselectable for arm.
I also threw in some documentation on this under kernel hardening in case other
arches decide to follow suit.

The plan is for this to go through the KSPP tree so if people are okay with
this, please give Acks. I didn't take Mark Rutland's ack from before since
there's been a bit of refactoring.

Thanks! I've added this to my KSPP -next tree. It should appear shortly...

Thanks,
Laura
