sparc32: drop swapper_pg_dir
We save one page of RAM dropping swapper_pg_dir. It was only used for an assignment in init-mm.c and we redid this later in srmmu.c anyway. This is likely a left-over from the sun4c removal. To avoid a dummy variable we use a simple #define swapper_pg_dir NULL Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
