      Pull user namespace updates from Eric Biederman:
       "This finishes up the changes to ensure proc and sysfs do not start
        implementing executable files, as the there are application today that
        are only secure because such files do not exist.
      
        It akso fixes a long standing misfeature of /proc/<pid>/mountinfo that
        did not show the proper source for files bind mounted from
        /proc/<pid>/ns/*.
      
        It also straightens out the handling of clone flags related to user
        namespaces, fixing an unnecessary failure of unshare(CLONE_NEWUSER)
        when files such as /proc/<pid>/environ are read while <pid> is calling
        unshare.  This winds up fixing a minor bug in unshare flag handling
        that dates back to the first version of unshare in the kernel.
      
        Finally, this fixes a minor regression caused by the introduction of
        sysfs_create_mount_point, which broke someone's in house application,
        by restoring the size of /sys/fs/cgroup to 0 bytes.  Apparently that
        application uses the directory size to determine if a tmpfs is mounted
        on /sys/fs/cgroup.
      
        The bind mount escape fixes are present in Al Viros for-next branch.
        and I expect them to come from there.  The bind mount escape is the
        last of the user namespace related security bugs that I am aware of"

        the plat-samsung directory is cleaned out by moving most of the
        previously shared-location-but-not-actually-shared files from there to
        the appropriate mach directories instead.

         - Rob Herring removed use of set_irq_flags under all platforms and
           moved to genirq alternatives

       "The main changes, mostly written by Frederic Weisbecker, include:
      
         - Fix some jiffies based cputime assumptions.  (No real harm because

         - Simplify jiffies <-> usecs conversions.  Remove dead code.
      
         - Remove early hacks on nohz full code that avoided messing up idle
           nohz internals.  Now nohz integrates well full and idle and such
           hack have become needless.
      
         - Restart nohz full tick from irq exit.  (A simplification and a
           preparation for future optimization on scheduler kick to nohz
           full)

       "The biggest change in this cycle is the rewrite of the main SMP load
        balancing metric: the CPU load/utilization.  The main goal was to make
        the metric more precise and more representative - see the changelog of
        this commit for the gory details:
      
          9d89c257 ("sched/fair: Rewrite runnable load and utilization average tracking")
      
        It is done in a way that significantly reduces complexity of the code:
      
          5 files changed, 249 insertions(+), 494 deletions(-)
      
        and the performance testing results are encouraging.  Nevertheless we
        need to keep an eye on potential regressions, since this potentially
        affects every SMP workload in existence.
      
        This work comes from Yuyang Du.

         - 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)

           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.
