Commita79ebea620(MIPS: ptrace: Fix user pt_regs definition, use in ptrace_{get, set}regs()) converted struct pt_regs to use __u64. Some userspace applications (e.g. GDB) include this file directly, and fail to see this type. Fix by including <linux/types.h>. The patch fixes the following build failure with GDB 7.8 when using GLIBC headers created against Linux 3.17: In file included from /home/aaro/los/work/shared/gdb-7.8/gdb/mips-linux-nat.c:37:0: /home/aaro/los/work/mips/rootfs/mips-linux-gnu/usr/include/asm/ptrace.h:32:2: error: unknown type name '__u64' __u64 regs[32]; ^ /home/aaro/los/work/mips/rootfs/mips-linux-gnu/usr/include/asm/ptrace.h:35:2: error: unknown type name '__u64' __u64 lo; ^ /home/aaro/los/work/mips/rootfs/mips-linux-gnu/usr/include/asm/ptrace.h:36:2: error: unknown type name '__u64' __u64 hi; ^ Fixes:a79ebea620("MIPS: ptrace: Fix user pt_regs definition, use in ptrace_{get, set}regs()") Cc: stable@vger.kernel.org # 3.17 Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Cc: Alex Smith <alex@alex-smith.me.uk> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/8067/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
