      Pull tracing fixes from Steven Rostedt:
       "User events:
      
         - Use long instead of int for storing the enable set/clear bit, as it
           was found that big endian machines could end up using the wrong
           bits.
      
         - Split allocating mm and attaching it. This keeps the allocation
           separate from the registration and avoids various races.
      
         - Remove RCU locking around pin_user_pages_remote() as that can
           schedule. The RCU protection is no longer needed with the above
           split of mm allocation and attaching.
      
         - Rename the "link" fields of the various structs to something more
           meaningful.
      
         - Add comments around user_event_mm struct usage and locking
           requirements.
      
        Timerlat tracer:
      
         - Fix missed wakeup of timerlat thread caused by the timerlat
           interrupt triggering when tracing is off. The timer interrupt
           handler needs to always wake up the timerlat thread regardless if
           tracing is enabled or not, otherwise, it will never wake up.
      
        Histograms:
      
         - Fix regression of breaking the "stacktrace" modifier for variables.
           That modifier cannot be used for values, but can be used for
           variables that are passed from one histogram to the next. This was
           broken when adding the restriction to values as the variable logic
           used the same code.
      
         - Rename the special field "stacktrace" to "common_stacktrace".
      
           Special fields (that are not actually part of the event, but can
           act just like event fields, like 'comm' and 'timestamp') should be
           prefixed with 'common_' for consistency. To keep backward
           compatibility, 'stacktrace' can still be used (as with the special
           field 'cpu'), but can be overridden if the event has a field called
           'stacktrace'.
      
         - Update the synthetic event selftests to use the new name (synthetic
           events are created by histograms)
      
        Tracing bootup selftests:
      
         - Reorganize the code to keep artifacts of the selftests not compiled
           in when selftests are not configured.
      
         - Add various cond_resched() around the selftest code, as the
           softlock watchdog was triggering much more often. It appears that
           the kernel runs slower now with full debugging enabled.
      
         - While debugging ftrace with ftrace (using an instance ring buffer
           instead of the top level one), I found that the selftests were
           disabling prints to the debug instance.
      
           This should not happen, as the selftests only disable printing to
           the main buffer as the selftests examine the main buffer to see if
           it has what it expects, and prints can make the tests fail.
      
           Make the selftests only disable printing to the toplevel buffer,
           and leave the instance buffers alone"

      Linus Torvalds authored
      This reverts commit 9828ed3f
      
      .
      
      Sadly, it does seem to cause failures to load modules. Johan Hovold reports:
      
       "This change breaks module loading during boot on the Lenovo Thinkpad
        X13s (aarch64).
      
        Specifically it results in indefinite probe deferral of the display
        and USB (ethernet) which makes it a pain to debug. Typing in the dark
        to acquire some logs reveals that other modules are missing as well"
      
      Since this was applied late as a "let's try this", I'm reverting it
      asap, and we can try to figure out what goes wrong later.  The excessive
      parallel module loading problem is annoying, but not noticeable in
      normal situations, and this was only meant as an optimistic workaround
      for a user-space bug.
      
      One possible solution may be to do the optimistic exclusive open first,
      and then use a lock to serialize loading if that fails.

      tracing: Have function_graph selftest call cond_resched() · a2d910f0
      Steven Rostedt (Google) authored
      When all kernel debugging is enabled (lockdep, KSAN, etc), the function
      graph enabling and disabling can take several seconds to complete. The
      function_graph selftest enables and disables function graph tracing
      several times. With full debugging enabled, the soft lockup watchdog was
      triggering because the selftest was running without ever scheduling.
      
      Add cond_resched() throughout the test to make sure it does not trigger
      the soft lockup detector.

      tracing: Only make selftest conditionals affect the global_trace · ac9d2cb1
      Steven Rostedt (Google) authored
      The tracing_selftest_running and tracing_selftest_disabled variables were
      to keep trace_printk() and other writes from affecting the tracing
      selftests, as the tracing selftests would examine the ring buffer to see
      if it contained what it expected or not. trace_printk() and friends could
      add to the ring buffer and cause the selftests to fail (and then disable
      the tracer that was being tested). To keep that from happening, these
      variables were added and would keep trace_printk() and friends from
      writing to the ring buffer while the tests were going on.
      
      But this was only the top level ring buffer (owned by the global_trace
      instance). There is no reason to prevent writing into ring buffers of
      other instances via the trace_array_printk() and friends. For the
      functions that could be used by other instances, check if the global_trace
      is the tracer instance that is being written to before deciding to not
      allow the write.

      tracing: Have tracer selftests call cond_resched() before running · 9da705d4
      Steven Rostedt (Google) authored
      As there are more and more internal selftests being added to the Linux
      kernel (KSAN, lockdep, etc) the selftests are taking longer to run when
      these are enabled. Add a cond_resched() to the calling of
      do_run_tracer_selftest() to force a schedule if NEED_RESCHED is set,
      otherwise the soft lockup watchdog may trigger on boot up.

      tracing: Move setting of tracing_selftest_running out of register_tracer() · e8352cf5
      Steven Rostedt (Google) authored
      The variables tracing_selftest_running and tracing_selftest_disabled are
      only used for when CONFIG_FTRACE_STARTUP_TEST is enabled. Make them only
      visible within the selftest code. The setting of those variables are in
      the register_tracer() call, and set in a location where they do not need
      to be. Create a wrapper around run_tracer_selftest() called
      do_run_tracer_selftest() which sets those variables, and have
      register_tracer() call that instead.
      
      Having those variables only set within the CONFIG_FTRACE_STARTUP_TEST
      scope gets rid of them (and also the ability to remove testing against
      them) when the startup tests are not enabled (most cases).

      cxl: Explicitly initialize resources when media is not ready · 793a539a
      Dave Jiang authored
      
      
      When media is not ready do not assume that the capacity information from
      the identify command is valid, i.e. ->total_bytes
      ->partition_align_bytes ->{volatile,persistent}_only_bytes. Explicitly
      zero out the capacity resources and exit early.
      
      Given zero-init of those fields this patch is functionally equivalent to
      the prior state, but it improves readability and robustness going
      forward.

      x86: re-introduce support for ERMS copies for user space accesses · 47ee3f1d
      Linus Torvalds authored
      I tried to streamline our user memory copy code fairly aggressively in
      commit adfcf423 ("x86: don't use REP_GOOD or ERMS for user memory
      copies"), in order to then be able to clean up the code and inline the
      modern FSRM case in commit 577e6a7f ("x86: inline the 'rep movs' in
      user copies for the FSRM case").
      
      We had reports [1] of that causing regressions earlier with blogbench,
      but that turned out to be a horrible benchmark for that case, and not a
      sufficient reason for re-instating "rep movsb" on older machines.
      
      However, now Eric Dumazet reported [2] a regression in performance that
      seems to be a rather more real benchmark, where due to the removal of
      "rep movs" a TCP stream over a 100Gbps network no longer reaches line
      speed.
      
      And it turns out that with the simplified the calling convention for the
      non-FSRM case in commit 427fda2c ("x86: improve on the non-rep
      'copy_user' function"), re-introducing the ERMS case is actually fairly
      simple.
      
      Of course, that "fairly simple" is glossing over several missteps due to
      having to fight our assembler alternative code.  This code really wanted
      to rewrite a conditional branch to have two different targets, but that
      made objtool sufficiently unhappy that this instead just ended up doing
      a choice between "jump to the unrolled loop, or use 'rep movsb'
      directly".
      
      Let's see if somebody finds a case where the kernel memory copies also
      care (see commit 68674f94: "x86: don't use REP_GOOD or ERMS for
      small memory copies").  But Eric does argue that the user copies are
      special because networking tries to copy up to 32KB at a time, if
      order-3 pages allocations are possible.
      
      In-kernel memory copies are typically small, unless they are the special
      "copy pages at a time" kind that still use "rep movs".

      Song Liu authored
      'struct evsel' uses a union for the two lists. This turned out to be
      error prone.
      
      For example:

        Error: cpu-clock event does not have sample flags 66c660
        failed to set filter "(null)" on event cpu-clock with 2 (No such file or directory)
        [root@quaco ~]# perf stat --bpf-prog 5246
      
      Fix this issue by separating the two lists.

      Copy the kernel version of the header to fix the header diff build
      warning. Some new definitions were only added to the tools side header,
      but these are only used in Perf so move them to a different header.
