sys/dev/pci : mpii.c
Log message:
use a mutex to ensure writes to the two registers used to post commands to
the chip are atomic wrt to all cpus in a system.
mpii_push_reply only writes to one reg, so it is already atomic. neither
it or mpii_start need splbio now.
mpii(4) is still not completely mpsafe cos all the sleeps done while
waiting for completion still rely on splbio.
