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

Module Name:    src
Committed By:   mhitch
Date:           Mon Nov  9 04:31:03 UTC 2009

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

Log Message:
The tlb shootdown IPI can interrupt the pool_cache_get() in places that
can cause a deadlock or pool cache corruption.  Take the shootdown job
queue mutex before calling pool_cache_get(), which will block the IPI
interrupts and seems to fix the remaining tlb shootdown deadlocks and
pool cache corruption I've been seeing.  Should address both
PR port-amiga/38335 and PR port-amiga/42174.
