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.
