[MIPS] Fixes for uaccess.h with gcc >= 4.0.1
It seems current get_user() incorrectly sign-extend an unsigned int value on 64bit kernel. I think this is because '(__typeof__(val))' cast in final assignment. I suppose the cast should be '(__typeof__(*(addr))'. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
