The newer code seems harder on the eyes and at least for i386, this
seems to produce larger code:

   text    data     bss     dec     hex filename
   4001      56       4    4061     fdd kern_synch.o.before
   4033      56       4    4093     ffd kern_synch.o.after

as it does for PowerPC:

   text    data     bss     dec     hex filename
   4872      56       4    4932    1344 kern_synch.o.before
   4884      56       4    4944    1350 kern_synch.o.after

For MIPS(el), the code size doesn't change at all:

   text    data     bss     dec     hex filename
   6132      64      16    6212    1844 kern_synch.o.before
   6132      64      16    6212    1844 kern_synch.o.after

although the generated code was a little different...
