Subject: [PATCH] csky: Add non-uapi asm/ptrace.h namespace

From: Guo Ren <ren_guo@...ky.com>

Move #ifdef __KERNEL__ code in the uapi namespace to non-uapi
include/asm/ptrace.h namespace and remove #ifdef __KERNEL__ in
include/asm/ptrace.h. Seperate ptrace.h in uapi and non-uapi is more
common and clear.
