From 3c46bdcaec53eda069a8a9cd60621c7431aa7842 Mon Sep 17 00:00:00 2001

Subject: [PATCH] m68k: implement __clear_user()
m68k: implement __clear_user(), which is needed by fs/signalfd.c
Since we always let the MMU do all checking, clear_user() and __clear_user()
are identical. The old clear_user() is renamed to __clear_user() for
consistency.
