[GIT PULL] probes: Updates for v6.14

[Masami Hiramatsu]

Hi Linus,

Probes updates for v6.14:

- kprobes: Cleanups using guard() and __free(): Use cleanup.h macros
  to cleanup code and remove all gotos from kprobes code. This work
  includes below changes.
  . kprobes: Adopt guard() and scoped_guard()
  . jump_label: Define guard() for jump_label_lock
  . kprobes: Use guard() for external locks
  . kprobes: Use guard for rcu_read_lock
  . kprobes: Remove unneeded goto
  . kprobes: Remove remaining gotos

- tracing/probes: Also cleanups tracing/*probe events code with guard()
  and __free(). These patches are just to simplify the parser codes.
  This work includes below changes.
  . tracing/kprobe: Adopt guard() and scoped_guard()
  . tracing/uprobe: Adopt guard() and scoped_guard()
  . tracing/eprobe: Adopt guard() and scoped_guard()
  . tracing: Use __free() in trace_probe for cleanup
  . tracing: Use __free() for kprobe events to cleanup
  . tracing/kprobes: Simplify __trace_kprobe_create() by removing gotos

- kprobes: Reduce preempt disable scope in check_kprobe_access_safe()
  This reduces preempt disable time only when getting the module
  refcount in check_kprobe_access_safe(). Previously it disabled
  preempt needlessly for other checks including
  jump_label_text_reserved(), but it took long time because of
  the linear search.
