 * splserial hack, idea by Jason Thorpe.
 * drivers which need it (at the present only the coms) raise the variable to
 * their serial interrupt level.
 *
 * serialspl is statically initialized in machdep.c at the moment; should
 * be some driver independent file.
 *
 * XXX should serialspl be volatile? I think not; it is intended to be set only
 * during xxx_attach() time, and will be used only later.
