      Pull tracing warning fix from Steven Rostedt:
       "Make the GCC 9 warning for sub struct memset go away.
      
        GCC 9 now warns about calling memset() on partial structures when it
        goes across multiple fields. This adds a helper for the place in
        tracing that does this type of clearing of a structure"

      tracing: Silence GCC 9 array bounds warning · 0c97bf86
      Miguel Ojeda authored
      Starting with GCC 9, -Warray-bounds detects cases when memset is called
      starting on a member of a struct but the size to be cleared ends up
      writing over further members.
      
      Such a call happens in the trace code to clear, at once, all members
      after and including `seq` on struct trace_iterator:
      
          In function 'memset',
              inlined from 'ftrace_dump' at kernel/trace/trace.c:8914:3:
          ./include/linux/string.h:344:9: warning: '__builtin_memset' offset
          [8505, 8560] from the object at 'iter' is out of the bounds of
          referenced subobject 'seq' with type 'struct trace_seq' at offset
          4368 [-Warray-bounds]
            344 |  return __builtin_memset(p, c, size);
                |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
      
      In order to avoid GCC complaining about it, we compute the address
      ourselves by adding the offsetof distance instead of referring
      directly to the member.
      
      Since there are two places doing this clear (trace.c and trace_kdb.c),
      take the chance to move the workaround into a single place in
      the internal header.

       "Here is another set of reviewed patches that adds SPDX tags to
        different kernel files, based on a set of rules that are being used to
        parse the comments to try to determine that the license of the file is
        "GPL-2.0-or-later".
      
        Only the "obvious" versions of these matches are included here, a
        number of "non-obvious" variants of text have been found but those
        have been postponed for later review and analysis.
      
        These patches have been out for review on the linux-spdx@vger mailing
        list, and while they were created by automatic tools, they were
        hand-verified by a bunch of different people, all whom names are on
        the patches are reviewers"

      locking/lock_events: Use this_cpu_add() when necessary · 51816e9e
      Waiman Long authored
      The kernel test robot has reported that the use of __this_cpu_add()
      causes bug messages like:
      
        BUG: using __this_cpu_add() in preemptible [00000000] code: ...
      
      Given the imprecise nature of the count and the possibility of resetting
      the count and doing the measurement again, this is not really a big
      problem to use the unprotected __this_cpu_*() functions.
      
      To make the preemption checking code happy, the this_cpu_*() functions
      will be used if CONFIG_DEBUG_PREEMPT is defined.
      
      The imprecise nature of the locking counts are also documented with
      the suggestion that we should run the measurement a few times with the
      counts reset in between to get a better picture of what is going on
      under the hood.
