The validation checks that the values that were just assigned, got
assigned i.e. the error can't ever happen.  Subsequent patches will call
this code in places where errors are not being returned.  Changing those
code paths to return this non-existent error is counter-productive, so
just remove it.

  # nrcpus online : 4
  # nrcpus avail : 4

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

  - In some cases where perf_event.fork.{pid,tid} should be used we were instead
    using perf_event.comm.{pid,tid}, which is not a problem for for the 'pid'
    case, that sits in the same place in these union_perf_event members, but
    comm.tid sits where fork.ppid is, oops.

    These cases were considered as (potentially) problematic:

     - 'perf script' with !sample_id_all, i.e. only non old kernels without
        perf_event_attr.sample_id_all.

     - intel_pt could be affected when decoding without timestamps, as the exit
       event is only used to flush out data which anyway gets flushed at the
       end of the session.

     - intel_bts also uses the exit event to flush data which would probably not
       cause errors as it would get flushed at the end of the session instead.

    Fix it. (Adrian Hunter)

  - Due to relaxing the compiler checks for bison generated files, we missed
    updating one parse_events_add_pmu() caller when this function had its
    prototype changed, fix it. (Jiri Olsa)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
Signed-off-by: Ingo Molnar <mingo@kernel.org>

In a couple of cases the 'comm' member of 'union event' has been used
instead of the correct member ('fork') when processing exit events.

In the cases where it has been used incorrectly, only the 'pid' and
'tid' are affected.  The 'pid' value would be correct anyway because it
is in the same position in 'comm' and 'fork' events, but the 'tid' would
have been incorrectly assigned from 'ppid'.

However, for exit events, the kernel puts the current task in the 'ppid'
and 'ttid' which is the same as the exiting task.  That is 'ppid' ==
'pid' and if the task is not multi-threaded, 'pid' == 'tid' i.e. the
data goes wrong only when tracing multi-threaded programs.

It is hard to find an example of how this would produce an error in
practice.  There are 3 occurences of the fix:

1. perf script is only affected if !sample_id_all which only happens on
  old kernels.

2. intel_pt is only affected when decoding without timestamps
   and would probably still decode correctly - the exit event is
   only used to flush out data which anyway gets flushed at the
   end of the session

3. intel_bts also uses the exit event to flush data which
   would probably not cause errors as it would get flushed at
   the end of the session instead

   - Add support for using several Intel PT features (CYC, MTC packets),
     the relevant documentation was updated in:
         tools/perf/Documentation/intel-pt.txt
     briefly describing those packets, its purposes, how to configure
     them in the event config terms and relevant external documentation
     for further reading.  (Adrian Hunter)

   - Introduce support for probing at an absolute address, for user and
     kernel 'perf probe's, useful when one have the symbol maps on a
     developer machine but not on an embedded system.  (Wang Nan)

   - Add Intel BTS support, with a call-graph script to show it and PT
     in use in a GUI using 'perf script' python scripting with
     postgresql and Qt.  (Adrian Hunter)

   - Allow selecting the type of callchains per event, including
     disabling callchains in all but one entry in an event list, to save
     space, and also to ask for the callchains collected in one event to
     be used in other events.  (Kan Liang)

   - Beautify more syscall arguments in 'perf trace': (Arnaldo Carvalho
     de Melo)
       * A bunch more translate file/pathnames from pointers to strings.
       * Convert numbers to strings for the 'keyctl' syscall 'option'
         arg.
       * Add missing 'clockid' entries.

   - Introduce 'srcfile' sort key: (Andi Kleen)

       # perf record -F 10000 usleep 1
       # perf report --stdio --dsos '[kernel.vmlinux]' -s srcfile
       <SNIP>
       # Overhead  Source File
          26.49%  copy_page_64.S
           5.49%  signal.c
           0.51%  msr.h
       #

     It can be combined with other fields, for instance, experiment with
     '-s srcfile,symbol'.

     There are some oddities in some distros and with some specific
     DSOs, being investigated, so your mileage may vary.

   - Support per-event 'freq' term: (Namhyung Kim)

       $ perf record -e 'cpu/instructions,freq=1234/',cycles -c 1000 sleep 1
       $ perf evlist -F
       cpu/instructions,freq=1234/: sample_freq=1234
       cycles: sample_period=1000
       $

   - Deref sys_enter pointer args with contents from probe:vfs_getname,
     showing pathnames instead of pointers in many syscalls in 'perf
     trace'.  (Arnaldo Carvalho de Melo)

   - Stop collecting /proc/kallsyms in perf.data files, saving about
     4.5MB on a typical x86-64 system, use the the symbol resolution
     routines used in all the other tools (report, top, etc) now that we
     can ask libtraceevent to use perf's symbol resolution code.
     (Arnaldo Carvalho de Melo)

   - Allow filtering out of perf's PID via 'perf record --exclude-perf'.
     (Wang Nan)

   - 'perf trace' now supports syscall groups, like strace, i.e:

       $ trace -e file touch file

     Will expand 'file' into multiple, file related, syscalls.  More
     work needed to add extra groups for other syscall groups, and also
     to complement what was added for the 'file' group, included as a
     proof of concept.  (Arnaldo Carvalho de Melo)

   - Add lock_pi stresser to 'perf bench futex', to test the kernel code
     related to FUTEX_(UN)LOCK_PI.  (Davidlohr Bueso)

   - Let user have timestamps with per-thread recording in 'perf record'
     (Adrian Hunter)

     details"

     otherwise result.

   - privatize smp_mb__after_unlock_lock().

     This commit moves the definition of smp_mb__after_unlock_lock() to
     kernel/rcu/tree.h, in recognition of the fact that RCU is the only
     thing using this, that nothing else is likely to use it, and that
     it is likely to go away completely.
