From: Geert Uytterhoeven Date: Tue, 15 May 2007 08:41:29 +0000 (-0700) Subject: m68k: implement __clear_user() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3c46bdcaec53eda069a8a9cd60621c7431aa7842;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git 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.
