Subject: m68k: implement __clear_user()
From: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx>
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.
