Subject: [GIT PULL] probes: Updates for v6.12

Hi Linus,

Probes updates for v6.12:

- uprobes: make trace_uprobe->nhit counter a per-CPU one
   This makes uprobe event's hit counter per-CPU for improving
   scalability on multi-core environment.

- kprobes: Remove obsoleted declaration for init_test_probes
   Remove unused init_test_probes() from header.

- Raw tracepoint probe supports raw tracepoint events on modules.
   The tracepoint events using fprobe were introduced in v6.5, but
   tracepoints can be compiled in modules. This supports such a case.
   This includes the following improvements.
  . tracepoint: add a function for iterating over all tracepoints in
    all modules.
  . tracepoint: Add a function for iterating over tracepoints in a
    module.
  . tracing/fprobe: Support raw tracepoint events on modules.
  . tracing/fprobe: Support raw tracepoints on future loaded modules.
     This allows user to add tracepoint events on modules which is
     not loaded yet.
  . selftests/tracing: Add a test for tracepoint events on modules.
