code. At this moment all architectures get the copy of the old code except i386 which gets a new shiny implementation that doesn't spin at splhigh (doh!) and doesn't try to grab the biglock when releasing the biglock (double doh!). Shaves 10% of system time during kernel compile and might solve a few bugs as a bonus. Other architectures coming shortly. miod@ deraadt@ ok
