We've always tried to stay within the tools/ source umbrella since we really
don't want to copy any more of the kernel than we have to, since otherwise,
we might as well go back to simplifying things and just building against the
entire kernel source tree.
I'd like to see if there's a way that we could limit this to the uapi (and
hence
use our uapi headers), and avoid needing to make the copy. If we need a
copy, then being as specific as possible would be the goal.
I'm not moving linux-yocto-dev to the latest -dev until next week, but I
can
look into this more then.
