       "This tree includes a single commit that speeds up x86 suspend/resume
        by replacing a naive 100msec sleep based polling loop with proper
        completion notification.
      
        This gives some real suspend/resume benefit on servers with larger
        core counts"

         - Re-enable inheritance optimization (Jiri Olsa)
      
         - Enhance Intel memory events support (Stephane Eranian)
      
         - Refactor the Intel uncore driver to be more maintainable (Zheng
           Yan)
      
         - Enhance and fix Intel CPU and uncore PMU drivers (Peter Zijlstra,
           Andi Kleen)
      
         - [ plus various smaller fixes/cleanups ]
      
        User visible tooling updates:
      
         - Add +field argument support for --field option, so that one can add
           fields to the default list of fields to show, ie now one can just
           do:
      
               perf report --fields +pid
      
           And the pid will appear in addition to the default fields (Jiri
           Olsa)
      
         - Add +field argument support for --sort option (Jiri Olsa)
      
         - Honour -w in the report tools (report, top), allowing to specify
           the widths for the histogram entries columns (Namhyung Kim)
      
         - Properly show submicrosecond times in 'perf kvm stat' (Christian
           Borntraeger)
      
         - Add beautifier for mremap flags param in 'trace' (Alex Snast)
      
         - perf script: Allow callchains if any event samples them
      
         - Don't truncate Intel style addresses in 'annotate' (Alex Converse)
      
         - Allow profiling when kptr_restrict == 1 for non root users, kernel
           samples will just remain unresolved (Andi Kleen)
      
         - Allow configuring default options for callchains in config file
           (Namhyung Kim)
      
         - Support operations for shared futexes.  (Davidlohr Bueso)
      
         - "perf kvm stat report" improvements by Alexander Yarygin:
             -  Save pid string in opts.target.pid
             -  Enable the target.system_wide flag
             -  Unify the title bar output
      
         - [ plus lots of other fixes and small improvements.  ]
      
        Tooling infrastructure changes:
      
         - Refactor unit and scale function parameters for PMU parsing
           routines (Matt Fleming)
      
         - Improve DSO long names lookup with rbtree, resulting in great
           speedup for workloads with lots of DSOs (Waiman Long)
      
         - We were not handling POLLHUP notifications for event file
           descriptors
      
           Fix it by filtering entries in the events file descriptor array
           after poll() returns, refcounting mmaps so that when the last fd
           pointing to a perf mmap goes away we do the unmap (Arnaldo Carvalho
           de Melo)
      
         - Intel PT prep work, from Adrian Hunter, including:
             - Let a user specify a PMU event without any config terms
             - Add perf-with-kcore script
             - Let default config be defined for a PMU
             - Add perf_pmu__scan_file()
             - Add a 'perf test' for tracking with sched_switch
             - Add 'flush' callback to scripting API
      
         - Use ring buffer consume method to look like other tools (Arnaldo
           Carvalho de Melo)
      
         - hists browser (used in top and report) refactorings, getting rid of
           unused variables and reducing source code size by handling similar
           cases in a fewer functions (Namhyung Kim).
      
         - Replace thread unsafe strerror() with strerror_r() accross the
           whole tools/perf/ tree (Masami Hiramatsu)
      
         - Rename ordered_samples to ordered_events and allow setting a queue
           size for ordering events (Jiri Olsa)

      Pull vfs updates from Al Viro:
       "The big thing in this pile is Eric's unmount-on-rmdir series; we
        finally have everything we need for that.  The final piece of prereqs
        is delayed mntput() - now filesystem shutdown always happens on
        shallow stack.
      
        Other than that, we have several new primitives for iov_iter (Matt
        Wilcox, culled from his XIP-related series) pushing the conversion to
        ->read_iter()/ ->write_iter() a bit more, a bunch of fs/dcache.c
        cleanups and fixes (including the external name refcounting, which
        gives consistent behaviour of d_move() wrt procfs symlinks for long
        and short names alike) and assorted cleanups and fixes all over the
        place.
      
        This is just the first pile; there's a lot of stuff from various
        people that ought to go in this window.  Starting with
        unionmount/overlayfs mess...  ;-/"
