  Log:
  In general, when we map a page into the kernel's address space, we no
  longer create a pv entry for that mapping.  (The two exceptions are
  mappings into the kernel's exec and pipe submaps.)  Consequently, there is
  no reason for get_pv_entry() to dig deep into the free page queues, i.e.,
  use VM_ALLOC_SYSTEM, by default.  This revision changes get_pv_entry() to
  use VM_ALLOC_NORMAL by default, i.e., before calling pmap_collect() to
  reclaim pv entries.
