Merge tag 'probes-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull probes updates from Masami Hiramatsu:

 - kprobes: Cleanups using guard() and __free(): Use cleanup.h macros to
   cleanup code and remove all gotos from kprobes code.

 - tracing/probes: Also cleanups tracing/*probe events code with guard()
   and __free(). These patches are just to simplify the parser codes.

 - kprobes: Reduce preempt disable scope in check_kprobe_access_safe()

   This reduces preempt disable time to only when getting the module
   refcount in check_kprobe_access_safe().

   Previously it disabled preempt needlessly for other checks including
   jump_label_text_reserved(), which took a long time because of the
   linear search.
