They don't work on general kernel memory, so I'd much prefer that these
weren't exported.

I see no users of set_memory_nx() in modules.  There's one module that
uses set_memory_x(), which is drivers/watchdog/hpwdt.c.  The three users
of that are ifdef'd for x86 cases, and it's used on the result of
ioremapping, which will fail on ARMs implementation (which only allows
modules memory.)
