gdb: add xtensa fixes for 7.5.1 



Two fixes for xtensa are still applicable to gdb-7.5.1, which is now the
default; copy them from 7.4.1. This fixes native gdb build for xtensa.

Subject: [PATCH] gdb: xtensa: fix linux ptrace includes



Currently, xtensa code using the Linux ptrace interface only include

sys/ptrace.h.  This file comes from the C library (glibc and uClibc,

at least), and includes a declaration of the ptrace() functions, along

with some cross architecture constants that are mostly copied from the

file located at include/uapi/linux/ptrace.h in recent Linux kernels.



For xtensa specific constants like PTRACE_GETXTREGS and

PTRACE_SETXTREGS the asm/ptrace.h include from the Linux kernel UAPI

is needed.  The code in gdbserver xtensa specific part doesn't call

ptrace() directly, so we can remove the unneeded sys/ptrace.h include.

The gdb xtensa specific code needs both headers, since it calls

ptrace().



gdb/

	* xtensa-linux-nat.c: Include asm/ptrace.h.



gdb/gdbserver/

	* linux-xtensa-low.c: Include asm/ptrace.h instead of

	sys/ptrace.h.
