The kernel use 64-bit for sc_regs[0], and both N32/N64 userland expects it was 64-bit. But size of 'long' on N32 is actually 32-bit. So this definition make some confusion. Use __u32 and __u64 for N32/N64 sigcontext to get rid of this confusion. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
