      Pull CXL (Compute Express Link) fixes from Dan Williams:
 "A collection of CXL fixes.

  The touch outside of drivers/cxl/ is for a helper that allocates
  physical address space. Device hotplug tests showed that the driver
  failed to utilize (skipped over) valid capacity when allocating a new
  memory region. Outside of that, new tests uncovered a small crop of
  lockdep reports.

  There is also some miscellaneous error path and leak fixups that are
  not urgent, but useful to cleanup now.

   - Fix alloc_free_mem_region()'s scan for address space, prevent false
     negative out-of-space events

   - Fix sleeping lock acquisition from CXL trace event (atomic context)

   - Fix put_device() like for the new CXL PMU driver

   - Fix wrong pointer freed on error path

   - Fixup several lockdep reports (missing lock hold) from new
     assertion in cxl_num_decoders_committed() and new tests"

      Merge tag 'trace-v6.7-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace · 3b8a9b2e
      Linus Torvalds authored 
      Pull tracing fixes from Steven Rostedt:

 - Fix eventfs to check creating new files for events with names greater
   than NAME_MAX. The eventfs lookup needs to check the return result of
   simple_lookup().

 - Fix the ring buffer to check the proper max data size. Events must be
   able to fit on the ring buffer sub-buffer, if it cannot, then it
   fails to be written and the logic to add the event is avoided. The
   code to check if an event can fit failed to add the possible absolute
   timestamp which may make the event not be able to fit. This causes
   the ring buffer to go into an infinite loop trying to find a
   sub-buffer that would fit the event. Luckily, there's a check that
   will bail out if it looped over a 1000 times and it also warns.

   The real fix is not to add the absolute timestamp to an event that is
   starting at the beginning of a sub-buffer because it uses the
   sub-buffer timestamp.

   By avoiding the timestamp at the start of the sub-buffer allows
   events that pass the first check to always find a sub-buffer that it
   can fit on.

 - Have large events that do not fit on a trace_seq to print "LINE TOO
   BIG" like it does for the trace_pipe instead of what it does now
   which is to silently drop the output.

 - Fix a memory leak of forgetting to free the spare page that is saved
   by a trace instance.

 - Update the size of the snapshot buffer when the main buffer is
   updated if the snapshot buffer is allocated.

 - Fix ring buffer timestamp logic by removing all the places that tried
   to put the before_stamp back to the write stamp so that the next
   event doesn't add an absolute timestamp. But each of these updates
   added a race where by making the two timestamp equal, it was
   validating the write_stamp so that it can be incorrectly used for
   calculating the delta of an event.

 - There's a temp buffer used for printing the event that was using the
   event data size for allocation when it needed to use the size of the
   entire event (meta-data and payload data)

 - For hardening, use "%.*s" for printing the trace_marker output, to
   limit the amount that is printed by the size of the event. This was
   discovered by development that added a bug that truncated the '\0'
   and caused a crash.

 - Fix a use-after-free bug in the use of the histogram files when an
   instance is being removed.

 - Remove a useless update in the rb_try_to_discard of the write_stamp.
   The before_stamp was already changed to force the next event to add
   an absolute timestamp that the write_stamp is not used. But the
   write_stamp is modified again using an unneeded 64-bit cmpxchg.

 - Fix several races in the 32-bit implementation of the
   rb_time_cmpxchg() that does a 64-bit cmpxchg.

 - While looking at fixing the 64-bit cmpxchg, I noticed that because
   the ring buffer uses normal cmpxchg, and this can be done in NMI
   context, there's some architectures that do not have a working
   cmpxchg in NMI context. For these architectures, fail recording
   events that happen in NMI context.

* tag 'trace-v6.7-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:
  ring-buffer: Do not record in NMI if the arch does not support cmpxchg in NMI
