Hmm, yes, I'll go with that, thanks (unless a better idea follows).

Something I do intend on top of what I sent before, is another set
of three macros, like

		if (pud_none_or_clear_bad(pud))
			continue;

to replace all the p??_none, p??_bad clauses: not to save space,
but just for clarity, those loops now seeming dominated by the
unlikeliest of cases.

Has anyone _ever_ seen a p??_ERROR message?  I'm inclined to just
put three functions into mm/memory.c to do the p??_ERROR and p??_clear,
but that way the __FILE__ and __LINE__ will always come out the same.
I think if it ever proves a problem, we'd just add in a dump_stack.
