[PATCH] kprobes: bugfix: checks kprobes_all_disarmed in unoptimized_kprobe().

[Wang Nan]

Hi Masami Hiramatsu,

I can't find this patch and '[PATCH] kprobes: bugfix: checks kprobes_all_disarmed
in unoptimized_kprobe().' in current mainline. How do these patches get there?
Should they be merged into Russell King's tree first?

Thank you!
