Eliminate all TLB shootdowns by pmap_pte_quick(): By temporarily pinning
the thread that calls pmap_pte_quick() and by virtue of the page queues
lock being held, we can manage PADDR1/PMAP1 as a CPU private mapping.
The most common effect of this change is to reduce the overhead of the page
daemon on multiprocessors.
