Alan Cox a087914310 Advance the state of pmap locking on alpha, amd64, and i386. ...

- Enable recursion on the page queues lock.  This allows calls to
   vm_page_alloc(VM_ALLOC_NORMAL) and UMA's obj_alloc() with the page
   queues lock held.  Such calls are made to allocate page table pages
   and pv entries.
 - The previous change enables a partial reversion of vm/vm_page.c
   revision 1.216, i.e., the call to vm_page_alloc() by vm_page_cowfault()
   now specifies VM_ALLOC_NORMAL rather than VM_ALLOC_INTERRUPT.
 - Add partial locking to pmap_copy().  (As a side-effect, pmap_copy()
   should now be faster on i386 SMP because it no longer generates IPIs
   for TLB shootdown on the other processors.)
 - Complete the locking of pmap_enter() and pmap_enter_quick().  (As of now,
   all changes to a user-level pmap on alpha, amd64, and i386 are performed
   with appropriate locking.)
