Kees Cook d2aa1acad2 mm/init: Add 'rodata=off' boot cmdline parameter to disable read-only kernel mappings ... It may be useful to debug writes to the readonly sections of memory, so provide a cmdline "rodata=off" to allow for this. This can be expanded in the future to support "log" and "write" modes, but that will need to be architecture-specific. This also makes KDB software breakpoints more usable, as read-only mappings can now be disabled on any kernel. Suggested-by: H.
