			The kernel's struct pt_regs has many fields conditional on various Kconfig variables, we cannot be exporting this garbage to user-space. Move the kernel's definition to asm/ptrace.h, and put a uapi only version in uapi/asm/ptrace.h gated by #ifndef __KERNEL__ Signed-off-by: David Daney <david.daney@cavium.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/5305/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
