With commit 63dc68a8, kernel can not handle BUG() and BUG_ON() properly since get_user() returns false for kernel code. Use __get_user() to skip unnecessary access_ok(). This patch also make BRK_BUG code encoded in the TNE instruction. Signed-off-by: NAtsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: NRalf Baechle <ralf@linux-mips.org>
