John Baldwin 23c31a3c5d Add locking to mcd(4) and mark MPSAFE. ... - Actually use existing per-softc mutex. - Use mutex in cdev routines and remove D_NEEDGIANT. - Use callout(9) instead of timeout(9). - Don't check for impossible conditions (e.g. MCDINIT being clear). - Remove critical_enter/exit when sending a PIO command. - Use bus_*() instead of bus_space_*().
