Nice! I just tried it out and got:

   text    data     bss     dec     hex filename
7747813 1673816 1503232 10924861         a6b33d vmlinux.old
7715443 1673560 1499136 10888139         a623cb vmlinux.new

Of course I have a lot of debugging enabled at the moment, which
probably exaggerates these numbers a bit. But still, 36K in savings is
nice for even a debug kernel :-)

I'll start beating on this patch for a bit, and will most likely add it
to my v3.10 queue.

Thanks!
