The philosophy of the kernel has always been that the backport needs
to bear the cost, and we don't want to add extra #ifdefs to the
standard kernel that don't do anything except in non-standard situations.

To be honest the patch that started this thread looked very reasonable
and easy to maintain to me.  The pain of backporting gets higher as
the kernel you're backporting to gets older, but that's just hte way
things are.
