Guided by grsecurity's analogous __read_only markings in arch/arm, this applies several uses of __ro_after_init to structures that are only updated during __init.

Hah, whooops. :)
That minor nit aside, these patches are a great step forward, are you going to take them and work to push them upstream, or do you want/need others to do this?
I'll collect more like these and carry a tree for -next and push them for v4.8. -Kees -- Kees Cook Chrome OS & Brillo Security
