    sys/vm               swap_pager.c vm_map.c vm_object.c 
    sys/i386/i386        pmap.c 
  Log:
  Avoid using the 64-bit vm_pindex_t in a few places where 64-bit
  types are not required, as the overhead is unnecessary:
  
   o In the i386 pmap_protect(), `sindex' and `eindex' represent page
     indices within the 32-bit virtual address space.
   o In swp_pager_meta_build() and swp_pager_meta_ctl(), use a temporary
     variable to store the low few bits of a vm_pindex_t that gets used
     as an array index.
   o vm_uiomove() uses `osize' and `idx' for page offsets within a
     map entry.
   o In vm_object_split(), `idx' is a page offset within a map entry.
