[PATCH 3.17 144/319] MIPS: ptrace.h: Add a missing include

3.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Aaro Koskinen <aaro.koskinen@iki.fi>

commit cdb685ad44996e9a113a10002cb42d40ff29db99 upstream.

Commit a79ebea62010 (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'
