      Pull perf updates from Ingo Molnar:
       "Kernel side updates:
      
         - Fix and enhance poll support (Jiri Olsa)
      
         - 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)
      
         - [ plus lots of fixes, cleanups and other improvements ]"

      xfs: fix agno increment in xfs_inumbers() loop · a8b1ee8b
      Eric Sandeen authored
      caused a regression in xfs_inumbers, which in turn broke
      xfsdump, causing incomplete dumps.
      
      The loop in xfs_inumbers() needs to fill the user-supplied
      buffers, and iterates via xfs_btree_increment, reading new
      ags as needed.
      
      But the first time through the loop, if xfs_btree_increment()
      succeeds, we continue, which triggers the ++agno at the bottom
      of the loop, and we skip to soon to the next ag - without
      the proper setup under next_ag to read the next ag.
      
      Fix this by removing the agno increment from the loop conditional,
      and only increment agno if we have actually hit the code under
      the next_ag: target.

      vfs: Deduplicate code shared by xattr system calls operating on paths · 8cc43116
      Eric Biggers authored
      The following pairs of system calls dealing with extended attributes only
      differ in their behavior on whether the symbolic link is followed (when
      the named file is a symbolic link):
      
      - setxattr() and lsetxattr()
      - getxattr() and lgetxattr()
      - listxattr() and llistxattr()
      - removexattr() and lremovexattr()
      
      Despite this, the implementations all had duplicated code, so this commit
      redirects each of the above pairs of system calls to a corresponding
      function to which different lookup flags (LOOKUP_FOLLOW or 0) are passed.
      
      For me this reduced the stripped size of xattr.o from 8824 to 8248 bytes.

       "This patch intentionally breaks the ABI on PARISC Linux!
      
        It assigns new numbers to SIGSTKFLT, SIGXCPU, SIGXFSZ and SIGSYS so
        that those are below 32 and thus leaves us with 32 RT signals like
        other Linux architectures (SIGRTMIN now becomes 32 instead of 37).
      
        Even if it breaks the ABI, it doesn't seem to have any visible impact
        on existing userspace applications.  I was able to mix new kernel
        and/or glibc without impacting normal bootup.  So, even if it breaks
        the ABI, the benefits (e.g.  being able to use systemd on PARISC
        Linux) outperforms the minimal (if any) impact it gives.
      
        The patch has been discussed on the parisc kernel mailing list and the
        coresponding glibc patch will be committed by the parisc glibc
        maintainer after this patch went into 3.18.

        reasons and excuses.

        that fairly unlikely anyway :^p    - Linus ]

       "This set has a few minor updates, but the big change is the redesign
        of the trampoline logic.
      
        The trampoline logic of 3.17 required a descriptor for every function
        that is registered to be traced and uses a trampoline.  Currently,
        only the function graph tracer uses a trampoline, but if you were to
        trace all 32,000 (give or take a few thousand) functions with the
        function graph tracer, it would create 32,000 descriptors to let us
        know that there's a trampoline associated with it.  This takes up a
        bit of memory when there's a better way to do it.
      
        The redesign now reuses the ftrace_ops' (what registers the function
        graph tracer) hash tables.  The hash tables tell ftrace what the
        tracer wants to trace or doesn't want to trace.  There's two of them:
        one that tells us what to trace, the other tells us what not to trace.
        If the first one is empty, it means all functions should be traced,
        otherwise only the ones that are listed should be.  The second hash
        table tells us what not to trace, and if it is empty, all functions
        may be traced, and if there's any listed, then those should not be
        traced even if they exist in the first hash table.
      
        It took a bit of massaging, but now these hashes can be used to keep
        track of what has a trampoline and what does not, and allows the
        ftrace accounting to work.  Now we can trace all functions when using
        the function graph trampoline, and avoid needing to create any special

      parisc: Reduce SIGRTMIN from 37 to 32 to behave like other Linux architectures · 1f25df2e
      Helge Deller authored
      This patch reduces the value of SIGRTMIN on PARISC from 37 to 32, thus
      increasing the number of available RT signals and bring it in sync with other
      Linux architectures.
      
      Historically we wanted to natively support HP-UX 32bit binaries with the
      PA-RISC Linux port.  Because of that we carried the various available signals
      from HP-UX (e.g. SIGEMT and SIGLOST) and folded them in between the native
      Linux signals.  Although this was the right decision at that time, this
      required us to increase SIGRTMIN to at least 37 which left us with 27 (64-37)
      RT signals.
      
      Those 27 RT signals haven't been a problem in the past, but with the upcoming
      importance of systemd we now got the problem that systemd alloctes (hardcoded)
      signals up to SIGRTMIN+29 which is beyond our NSIG of 64. Because of that we
      have not been able to use systemd on the PARISC Linux port yet.
      
      Of course we could ask the systemd developers to not use those hardcoded
      values, but this change is very unlikely, esp. with PA-RISC being a niche
      architecture.
      
      The other possibility would be to increase NSIG to e.g. 128, but this would
      mean to duplicate most of the existing Linux signal handling code into the
      parisc specific Linux kernel tree which would most likely introduce lots of new
      bugs beside the code duplication.
      
      The third option is to drop some HP-UX signals and shuffle some other signals
      around to bring SIGRTMIN to 32.  This is of course an ABI change, but testing
      has shown that existing Linux installations are not visibly affected by this
      change - most likely because we move those signals around which are rarely used
      and move them to slots which haven't been used in Linux yet. In an existing
      installation I was able to exchange either the Linux kernel or glibc (or both)
      without affecting the boot process and installed applications.
      
      Dropping the HP-UX signals isn't an issue either, since support for HP-UX was
      basically dropped a few months back with Kernel 3.14 in commit
      f5a408d5 already, when we changed EWOULDBLOCK
      to be equal to EAGAIN.
      
      So, even if this is an ABI change, it's better to change it now and thus bring
      PARISC Linux in sync with other architectures to avoid other issues in the
      future.

       "Here's a first pull request for powerpc updates for 3.18.
      
        The bulk of the additions are for the "cxl" driver, for IBM's Coherent
        Accelerator Processor Interface (CAPI).  Most of it's in drivers/misc,
        which Greg & Arnd maintain, Greg said he was happy for us to take it
        through our tree.
      
        There's the usual minor cleanups and fixes, including a bit of noise
        in drivers from some of those.  A bunch of updates to our EEH code,
        which has been getting more testing.  Several nice speedups from
        Anton, including 20% in clear_page().
      
        And a bunch of updates for freescale from Scott"

      Pull sound updates from Takashi Iwai:
       "This time it's a relatively calm update batch, but the amount isn't
        too small in the end.  Here we go over some highlights:
      
        ALSA core:
         - One major change is the support of nonatomic PCM operations.  This
           allows the trigger and other callbacks to call schedule(), which
           would be useful for mailbox type communications.  Already some
           drivers (Digigram ones) have been converted to use together with
           threaded irqs as an example.
         - Improvement / fixes of DSD PCM format support
      
        HD-audio:
         - Large volume of rewrites are found in Realtek codec driver for
           converting Dell and HP quirks to generic forms.
         - Inverted dmic code cleanup from David.
         - Realtek COEF access has been optimized.
         - Now HD-audio jack infrastructure allows multiple callbacks, which
           fixes / simplifies the jack-dependent power controls on STAC/IDT
           and VIA codecs.
         - Many additional device-specific fixups as usual
         - A few deadcode cleanups, CA0132 code cleanup, etc.
      
        ASoC:
         - More componentization work from Lars-Peter, this time mainly
           cleaning up the suspend and bias level transition callbacks.
         - Real system support for the Intel drivers and a bunch of fixes and
           enhancements for the associated CODEC drivers, this is going to
           need a lot quirks over time due to the lack of any firmware
           description of the boards.
         - Jack detect support for simple card from Dylan Reid.
         - A bunch of small fixes and enhancements for the Freescale drivers.
         - New drivers for Analog Devices SSM4567, Cirrus Logic CS35L32,
