  Modified:    sys/sys   mman.h
               sys/vm    swap_pager.c swap_pager.h vm_map.c vm_object.c
  Log:
  Initial support for MADV_FREE, support for pages that we don't care
  about the contents anymore.  This gives us alot of the advantage of
  freeing individual pages through munmap, but with almost none of the
  overhead.
