Merge tag 'probes-v7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux...

Pull kprobes updates from Masami Hiramatsu:

 - Use a dedicated kernel thread to optimize the kprobes instead of
   using workqueue thread. Since the kprobe optimizer waits a long time
   for synchronize_rcu_task(), it can block other workers in the same
   queue if it uses a workqueue.

 - kprobe-events: return immediately if no new probe events are
   specified on the kernel command line at boot time. This shortens
   the kernel boot time.

 - When a kprobe is fully removed from the kernel code, retry optimizing
   another kprobe which is blocked by that kprobe.
