SubjectRe: include/linux/kprobes.h:361:2: error: invalid use of undefined type 'struct kprobe_ctlblk'

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.
