There's a *LOT* of content to read for a reviewer to figure out what's
going on here between all the links.  I would have appreciated one more
sentence here, maybe:

	This is now safe because the sysctl registration code
	(register_sysctl()) implicitly uses ARRAY_SIZE() in addition
	to checking for a sentinel.

That needs to be more prominent _somewhere_.  Maybe here, or maybe in
the cover letter, but _somewhere_.

That said, feel free to add this to the two x86 patches:
