The only user right now is mm/memory.c, and it doesn't even include
<asm/ptrace.h>, but instead does the proper thing and includes
<linux/ptrace.h>
So please make <linux/ptrace.h> just do
#ifndef exception_ip
#define exception_ip(x) instruction_pointer(x)
#endif
and all those non-MIPS architecture updates should just go away, and
the diffstat should look something like
arch/mips/kernel/ptrace.c | 7 +++++++
include/linux/ptrace.h | 4 ++++
mm/memory.c | 4 ++--
instead.
