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: add #include asm/ptrace.h.
gdb/gdbserver/
* linux-xtensa-low.c: #include asm/ptrace.h instead of sys/ptrace.h.

It would be nice to have this and the other xtensa fix in the 7.6 and 7.7
branches as well.
Thanks,
