- Tidy up: Add comments.  Eliminate the pointless
  malloc_type_allocated(..., 0) calls that occur when contigmalloc() has
  failed.  Eliminate the acquisition and release of the page queues lock
  from vm_page_release_contig().  Rename contigmalloc2() to
  contigmapping(), reflecting what it does.
- Make contigmalloc(9)'s page laundering more robust.  Specifically, use
  vm_pageout_fallback_object_lock() in vm_contig_launder_page() to better
  handle a lock-ordering problem.  Consequently, trylock's failure on the
  page's containing object no longer implies that the page cannot be
  laundered.
