I didn't even know this existed until David submitted a patch set that included updates to the documentation as a result of some features he added to RISC-V. It looks like there may be a handful of other people who don't know this exists either, so I figured I'd just mail out a patch set containing all the updates split out as well as I can. This smells like something that sholud be automatic, so if I'm jumping the gun here then feel free to drop this. If nobody says anything then I guess I'll submit this as a separate PR to Linus from my personal tree, as it's not really a RISC-V thing but it seems like it's worth having docs that match the code where it's trivial -- I assume that's what this does, I didn't actually read anything but the diff because I never trust documentation to be up to date... I feel compelled to say something like "maybe this should be part of checkpatch?", but I'm definately not looking to learn perl :)
