Nor does the core kernel kprobes code. So these are arch-specific things and shouldn't be referenced from include/linux/kprobes.h at all. I think - I didn't look super-closely at it. So an appropriate fix for this would be to move the references to prev_kprobe/kprobe_ctlblk out of include/linux/kprobes.h and into asm/kprobes.h. Presumably via include/asm-generic/kprobes.h in some fashion. Have you tested this patch on mn10300? Does kprobes actually work on mn10300? Perhaps not, and the solution here is to disable kprobes on that arch until someone fixes it all up. Please resend any mn10300 fixes which you still have pending. Please be a bit more sparing in the cc's when doing so ;) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
