Modified Files:
	syssrc/sys/arch/alpha/alpha: vm_machdep.c

Log Message:
In cpu_fork(), initialize u_pcb.pcb_context[8] so that the newly
spawned kthread/process runs at IPL_0 instead of whatever IPL the
parent was running at.

This appears to fix the NTP clock stability problems observed on some
alpha systems; the clock appears stable even when there's heavy
raidframe (i.e., kthread-intensive) I/O under way.
