I actually needed something I could use in code that only
works on 2.6.9 kernels, where <linux/compiler.h> doesn't
handle "-Wcontext"; that board isn't on 2.6.10-rc yet, I
needed other version-specific #ifdefs too.

Sounds fine to me, and I'll send Greg a patch doing that for
all the HCDs. I was a bit more concerned with whether that
particular locking policy "should" get changed at some point;
at least, it's one to only adopt with caution.
Thanks for the feedback!
