Update of /cvsroot/src/sys/arch/alpha/alpha
In directory netbsd1:/var/slash-tmp/cvs-serv24034/alpha

Modified Files:
	autoconf.c machdep.c 
Log Message:
fix slight bogons in splhigh() usage, that were introduced when the
behaviour of splhigh() was changed.  The new behaviour raised the level to
IPL_HIGH if it was lower, but left it alone if the same or higher.  Apparently
the firmware transfers to NetBSD with all interrupts blocked, or something
else blocks all interrupts (including machine checks) before the code
is really started.  This meant that machine checks were blocked during
device probes, leading to false device probes _and_ an unexpected (and
therefore fatal) machine check at the spl0() after autoconfiguration.
