Good idea, that. The ppc64 guys (guy) don't actually want the feature,
and it significantly de-risks things. Although it's one more datapoint
to be gathered when pondering oops reports.

Stylistic trivia: When stubbing out a function it's cleaner (and faster)
to do:

#ifdef CONFIG_FOO
int my_function(arg1, arg2)
{
...
}
#else
static inline int my_function(arg1, arg2)
{
return 0;
}
#endif

Do we have any performance numbers on this yet? Both for speed
and space?
