lib/nmi-backtrace.c needs linux/kprobes.h to get at the definition of
NOKPROBE_SYMBOL().
I guess MN10300 does not support CONFIG_KPROBES=y. CONFIG_KPROBES=y
requires the architecture asm/kprobes.h to define this structure,
and mn10300 does not.
I guess that as things like the scheduler also include linux/kprobes.h,
this is not the only instance of this error when building mn10300 with
KPROBES enabled.
So, I guess that there's nothing that can be done about the build error
other than "don't build mn10300 with KPROBES enabled".

The facts of this are:
linux/kprobes.h includes asm/kprobes.h
linux/kprobes.h wants the architecture to define struct kprobe_ctlblk.
arch/mn10300/include/asm/kprobes.h fails to define this structure.
So, I've no idea how kprobes can even work on this architecture. AFAICS
it should not allow kprobes to be enabled.
This problem needs resolving by the mn10300 maintainer. I can do nothing
about it.

Sorry, I've no clue about this. From what I can see, kprobes.h is
correct.
#ifdef CONFIG_KPROBES
DECLARE_PER_CPU(struct kprobe *, current_kprobe);
DECLARE_PER_CPU(struct kprobe_ctlblk, kprobe_ctlblk);
...
static inline struct kprobe_ctlblk *get_kprobe_ctlblk(void)
{
return this_cpu_ptr(&kprobe_ctlblk);
}
The only way I can see that kprobe_ctlblk would be undefined is if
MN10300 were doing something totally weird with DECLARE_PER_CPU().
Since I know precisely nothing about MN10300, and it doesn't seem to
touch the definition of DECLARE_PER_CPU(), I'm at a total loss to
understand how this error can occur.
Some help would be nice - as right now I have absolutely no idea on
this.
