I'm trying to 'suddenly redefine' kernel headers as something that
_isn't_ just a library of random crap for people to abuse in userspace
as they see fit, then whine when something breaks even though it was
never really guaranteed to work when abused in that way anyway.

So far, you're just reminding me why that needed to be done.

Really? You used them as a reference implementation? Didn't you already
know how x86_64 syscalls work?

Or were you saying you just happened to use the x86_64 implementation of
_syscallX stuff in some userspace hacks, and it happened to work? In
which case go and line up behind the guy who said that about atomic.h on
i386 and only ever tested it on UP. The doctor will get to you later.
