        sys/arch/alpha/alpha/pmap.c: revision 1.250
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-alpha/38335 and PR port-alpha/42174.
