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.
