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:
