Pull clone3 fix from Christian Brauner:
 "A simple fix for the clone3() system call.

  The CLONE_NEWTIME allows the creation of time namespaces. The flag
  reuses a bit from the CSIGNAL bits that are used in the legacy clone()
  system call to set the signal that gets sent to the parent after the
  child exits.

  The clone3() system call doesn't rely on CSIGNAL anymore as it uses a
  dedicated .exit_signal field in struct clone_args. So we blocked all
  CSIGNAL bits in clone3_args_valid(). When CLONE_NEWTIME was introduced
  and reused a CSIGNAL bit we forgot to adapt clone3_args_valid()
  causing CLONE_NEWTIME with clone3() to be rejected. Fix this"

Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Add Adrian Hunter to MAINTAINERS as a perf tools reviewer

 - Sync various tools/ copies of kernel headers with the kernel sources,
   this time trying to avoid first merging with upstream to then update
   but instead copy from upstream so that a merge is avoided and the end
   result after merging this pull request is the one expected,
   tools/perf/check-headers.sh (mostly) happy, less warnings while
   building tools/perf/

 - Fix counting when initial delay configured by setting
   perf_attr.enable_on_exec when starting workloads from the perf
   command line

 - Don't avoid emitting a PERF_RECORD_MMAP2 in 'perf inject
   --buildid-all' when that record comes with a build-id, otherwise we
   end up not being able to resolve symbols

 - Don't use comma as the CSV output separator the "stat+csv_output"
   test, as comma can appear on some tests as a modifier for an event,
   use @ instead, ditto for the JSON linter test

 - The offcpu test was looking for some bits being set on
   task_struct->prev_state without masking other bits not important for
   this specific 'perf test', fix it

Lorenzo points out that the generic CLI is broken for the netdev
family. When I added the support for documentation of enums
(and sparse enums) the client script was not updated.
It expects the values in enum to be a list of names,
now it can also be a dict (YAML object).

I was intending to make all the Netlink Spec code BSD-3-Clause
to ease the adoption but it appears that:
 - I fumbled the uAPI and used "GPL WITH uAPI note" there
 - it gives people pause as they expect GPL in the kernel
As suggested by Chuck re-license under dual. This gives us benefit
of full BSD freedom while fulfilling the broad "kernel is under GPL"
expectations.
