i don't think splitting the path addresses the contention.  Joseph's
point (which i agree with) is that linux/generic/ is for the "generic
ABI" which the kernel is trying to push for new arches.  if you have
stuff which works across all linux ABI's, then instead of being in
linux/generic/xxx, it should be in linux/xxx.

if that means some things get hoisted out of linux/generic/xxx and
into linux/xxx, then that's OK.
