Modified files:
sys/isa sio.c
Log:
Convert the sio driver to use a spin mutex instead of a s_lock. This is
going to hurt sio(4) performance for the time being. As we get closer to
release and have more of the kernel unlocked we can come back to doing
arcane optimizations to workaround the limitations of the sio hardware.
