CVS commit: src/sys/arch/alpha/alpha

Module Name:    src
Committed By:   mhitch
Date:           Sun Oct  4 17:00:31 UTC 2009

Modified Files:
        src/sys/arch/alpha/alpha: pmap.c

Log Message:
IPI interrupts occur above IPL_VM, so using IPL_VM in for the tlb shootdown
queue mutex doesn't work very well.  I get various deadlocks and corrupted
queue entries.  Change to IPL_SCHED [IPL_CLOCK] to block IPI interrupts
while the cpu is mucking with the shootdown queue.
