Linus Torvalds cc998ff881 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next 
Pull networking changes from David Miller:
 "Noteworthy changes this time around:

   1) Multicast rejoin support for team driver, from Jiri Pirko.

   2) Centralize and simplify TCP RTT measurement handling in order to
      reduce the impact of bad RTO seeding from SYN/ACKs.  Also, when
      both timestamps and local RTT measurements are available prefer
      the later because there are broken middleware devices which
      scramble the timestamp.

      From Yuchung Cheng.

   3) Add TCP_NOTSENT_LOWAT socket option to limit the amount of kernel
      memory consumed to queue up unsend user data.  From Eric Dumazet.

   4) Add a "physical port ID" abstraction for network devices, from
      Jiri Pirko.

   5) Add a "suppress" operation to influence fib_rules lookups, from
      Stefan Tomanek.

   6) Add a networking development FAQ, from Paul Gortmaker.

   7) Extend the information provided by tcp_probe and add ipv6 support,
      from Daniel Borkmann.

   8) Use RCU locking more extensively in openvswitch data paths, from
      Pravin B Shelar.

   9) Add SCTP support to openvswitch, from Joe Stringer.

  10) Add EF10 chip support to SFC driver, from Ben Hutchings.

  11) Add new SYNPROXY netfilter target, from Patrick McHardy.

  12) Compute a rate approximation for sending in TCP sockets, and use
      this to more intelligently coalesce TSO frames.  Furthermore, add
      a new packet scheduler which takes advantage of this estimate when
      available.  From Eric Dumazet.

  13) Allow AF_PACKET fanouts with random selection, from Daniel
      Borkmann.

  14) Add ipv6 support to vxlan driver, from Cong Wang"

David S. Miller 06c54055be Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net 
Conflicts:
	drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c
	net/bridge/br_multicast.c
	net/ipv6/sit.c

The conflicts were minor:

1) sit.c changes overlap with change to ip_tunnel_xmit() signature.

2) br_multicast.c had an overlap between computing max_delay using
   msecs_to_jiffies and turning MLDV2_MRC() into an inline function
   with a name using lowercase instead of uppercase letters.

3) stmmac had two overlapping changes, one which conditionally allocated
   and hooked up a dma_cfg based upon the presence of the pbl OF property,
   and another one handling store-and-forward DMA made.  The latter of
   which should not go into the new of_find_property() basic block.

Merge tag 'fbdev-3.12-omap-legacy-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux

Pull OMAP specific fbdev changes from Tomi Valkeinen:
 "I've got this pull request separate from the main fbdev pull request,
  as this contains a bunch of OMAP board file changes and thus could
  possibly be rejected in case of bad conflicts.

  The removal of the old display drivers depend on the board file
  changes, so Tony Lindgren suggested taking them together via fbdev
  tree.  These are in linux-next, and also Tony didn't see any conflicts
  with any of the branches he had, so they should go in clean.

   - Change the OMAP board files to use the new OMAP display drivers

   - Remove all the old drivers, and the related auxiliary code"

  but eventually there will be less of me doing the Xen GIT pulls and
  more of them.  Stefano is still doing the ARM/ARM64 and will continue
  on doing so.

  Features:
   - Xen Trusted Platform Module (TPM) frontend driver - with the
     backend in MiniOS.
   - Scalability improvements in event channel.
   - Two extra Xen co-maintainers (David, Boris) and one going away (Jeremy)

  Bug-fixes:
   - Make the 1:1 mapping work during early bootup on selective regions.
   - Add scratch page to balloon driver to deal with unexpected code
     still holding on stale pages.
   - Allow NMIs on PV guests (64-bit only)
   - Remove unnecessary TLB flush in M2P code.
   - Fixes duplicate callbacks in Xen granttable code.
   - Fixes in PRIVCMD_MMAPBATCH ioctls to allow retries
   - Fix for events being lost due to rescheduling on different VCPUs.
   - More documentation"

Linus Torvalds 27703bb4a6 PTR_RET() is a weird name, and led to some confusing usage. We ended 
up with PTR_ERR_OR_ZERO(), and replacing or fixing all the usages.
 
 This has been sitting in linux-next for a whole cycle.

Linus Torvalds aa7054f5a5 Bulk pin control changes for the v3.12 series: 
- Refactorings for generic pin config handling in the core.
 
 - Factor out a set of device tree utilities for use in all
   drivers, to parse and allocate maps from the device tree.
 
 - Some fixes to the core such as more nitpicky locking.
 
 - Pushed down config array iteration into the drivers.
   This patch is necessary for drivers that want to iterate
   over configs and pile up a stack of alterations to the
   same register(s), or if the driver wants to take a local
   spinlock when committing the configuration.
 
 - A new driver for the Texas Instruments Palmas PMIC by

Pull pin control changes from Linus Walleij:
 "Here is the bulk of pin control changes for the v3.12 series.  Most of
  the relevant information is in the tag.

  I merged in v3.11-rc7 last week to get rid of a largeish conflict
  within the sunxi (AllWinner) driver in linux-next and fix up the
  non-trivial merge the right way.  That driver had a rather large fix
  adding locking late in the release cycle.

  Overall the bulk changes this time is cleanups and refactorings and
  not much new features, which is nice.

   - Refactorings for generic pin config handling in the core.

   - Factor out a set of device tree utilities for use in all drivers,
     to parse and allocate maps from the device tree.

   - Some fixes to the core such as more nitpicky locking.

Linus Torvalds 0d99b70873 Merge branches 'perf-urgent-for-linus' and 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 
Pull perf changes from Ingo Molnar:
 "As a first remark I'd like to point out that the obsolete '-f'
  (--force) option, which has not done anything for several releases,
  has been removed from 'perf record' and related utilities.  Everyone
  please update muscle memory accordingly! :-)

  Main changes on the perf kernel side:

   - Performance optimizations:
        . for trace events, by Steve Rostedt.
        . for time values, by Peter Zijlstra

   - New hardware support:
        . for Intel Silvermont (22nm Atom) CPUs, by Zheng Yan
        . for Intel SNB-EP uncore PMUs, by Zheng Yan

   - Enhanced hardware support:
        . for Intel uncore PMUs: add filter support for QPI boxes, by Zheng Yan

   - Core perf events code enhancements and fixes:
        . for full-nohz feature handling, by Frederic Weisbecker
        . for group events, by Jiri Olsa
        . for call chains, by Frederic Weisbecker
        . for event stream parsing, by Adrian Hunter

   - New ABI details:
        . Add attr->mmap2 attribute, by Stephane Eranian
        . Add PERF_EVENT_IOC_ID ioctl to return event ID, by Jiri Olsa
        . Export u64 time_zero on the mmap header page to allow TSC
          calculation, by Adrian Hunter
        . Add dummy software event, by Adrian Hunter.
        . Add a new PERF_SAMPLE_IDENTIFIER to make samples always
          parseable, by Adrian Hunter.
        . Make Power7 events available via sysfs, by Runzhen Wang.

   - Code cleanups and refactorings:
        . for nohz-full, by Frederic Weisbecker
        . for group events, by Jiri Olsa

   - Documentation updates:
        . for perf_event_type, by Peter Zijlstra

  Main changes on the perf tooling side (some of these tooling changes
  utilize the above kernel side changes):

   - Lots of 'perf trace' enhancements:

        . Make 'perf trace' command line arguments consistent with
          'perf record', by David Ahern.

        . Allow specifying syscalls a la strace, by Arnaldo Carvalho de Melo.

        . Add --verbose and -o/--output options, by Arnaldo Carvalho de Melo.

        . Support ! in -e expressions, to filter a list of syscalls,
          by Arnaldo Carvalho de Melo.

        . Arg formatting improvements to allow masking arguments in
          syscalls such as futex and open, where the some arguments are
          ignored and thus should not be printed depending on other args,
          by Arnaldo Carvalho de Melo.

        . Beautify futex open, openat, open_by_handle_at, lseek and futex
          syscalls, by Arnaldo Carvalho de Melo.

        . Add option to analyze events in a file versus live, so that
          one can do:

           [root@zoo ~]# perf record -a -e raw_syscalls:* sleep 1
           [ perf record: Woken up 0 times to write data ]
           [ perf record: Captured and wrote 25.150 MB perf.data (~1098836 samples) ]
           [root@zoo ~]# perf trace -i perf.data -e futex --duration 1
              17.799 ( 1.020 ms): 7127 futex(uaddr: 0x7fff3f6c6674, op: 393, val: 1, utime: 0x7fff3f6c6470, ua
             113.344 (95.429 ms): 7127 futex(uaddr: 0x7fff3f6c6674, op: 393, val: 1, utime: 0x7fff3f6c6470, uaddr2: 0x7fff3f6c6648, val3: 4294967
             133.778 ( 1.042 ms): 18004 futex(uaddr: 0x7fff3f6c6674, op: 393, val: 1, utime: 0x7fff3f6c6470, uaddr2: 0x7fff3f6c6648, val3: 429496
           [root@zoo ~]#

          By David Ahern.

        . Honor target pid / tid options when analyzing a file, by David Ahern.

        . Introduce better formatting of syscall arguments, including so
          far beautifiers for mmap, madvise, syscall return values,
          by Arnaldo Carvalho de Melo.

        . Handle HUGEPAGE defines in the mmap beautifier, by David Ahern.

   - 'perf report/top' enhancements:

        . Do annotation using /proc/kcore and /proc/kallsyms when
          available, removing the forced need for a vmlinux file kernel
          assembly annotation. This also improves this use case because
          vmlinux has just the initial kernel image, not what is actually
          in use after various code patchings by things like alternatives.
          By Adrian Hunter.

        . Add --ignore-callees=<regex> option to collapse undesired parts
          of call graphs, by Greg Price.

        . Simplify symbol filtering by doing it at machine class level,
          by Adrian Hunter.

        . Add support for callchains in the gtk UI, by Namhyung Kim.

        . Add --objdump option to 'perf top', by Sukadev Bhattiprolu.

   - 'perf kvm' enhancements:

        . Add option to print only events that exceed a specified time
          duration, by David Ahern.

        . Improve stack trace printing, by David Ahern.

        . Update documentation of the live command, by David Ahern

        . Add perf kvm stat live mode that combines aspects of 'perf kvm
          stat' record and report, by David Ahern.

        . Add option to analyze specific VM in perf kvm stat report, by
          David Ahern.

        . Do not require /lib/modules/* on a guest, by Jason Wessel.

   - 'perf script' enhancements:

        . Fix symbol offset computation for some dsos, by David Ahern.

        . Fix named threads support, by David Ahern.

        . Don't install scripting files files when perl/python support
          is disabled, by Arnaldo Carvalho de Melo.

   - 'perf test' enhancements:

        . Add various improvements and fixes to the "vmlinux matches
          kallsyms" 'perf test' entry, related to the /proc/kcore
          annotation feature. By Adrian Hunter.

        . Add sample parsing test, by Adrian Hunter.

        . Add test for reading object code, by Adrian Hunter.

        . Add attr record group sampling test, by Jiri Olsa.

        . Misc testing infrastructure improvements and other details,
          by Jiri Olsa.

   - 'perf list' enhancements:

        . Skip unsupported hardware events, by Namhyung Kim.

        . List pmu events, by Andi Kleen.

   - 'perf diff' enhancements:

        . Add support for more than two files comparison, by Jiri Olsa.

   - 'perf sched' enhancements:

        . Various improvements, including removing reliance on some
          scheduler tracepoints that provide the same information as the
          PERF_RECORD_{FORK,EXIT} events. By David Ahern.

        . Remove odd build stall by moving a large struct initialization
          from a local variable to a global one, by Namhyung Kim.

   - 'perf stat' enhancements:

        . Add --initial-delay option to skip measuring for a defined
          startup phase, by Andi Kleen.

   - Generic perf tooling infrastructure/plumbing changes:

        . Tidy up sample parsing validation, by Adrian Hunter.

        . Fix up jobserver setup in libtraceevent Makefile.
          by Arnaldo Carvalho de Melo.

        . Debug improvements, by Adrian Hunter.

        . Fix correlation of samples coming after PERF_RECORD_EXIT event,
          by David Ahern.

        . Improve robustness of the topology parsing code,
          by Stephane Eranian.

        . Add group leader sampling, that allows just one event in a group
          to sample while the other events have just its values read,
          by Jiri Olsa.

        . Add support for a new modifier "D", which requests that the
          event, or group of events, be pinned to the PMU.
          By Michael Ellerman.

        . Support callchain sorting based on addresses, by Andi Kleen

        . Prep work for multi perf data file storage, by Jiri Olsa.

        . libtraceevent cleanups, by Namhyung Kim.

  And lots and lots of other fixes and code reorganizations that did not
  make it into the list, see the shortlog, diffstat and the Git log for
  details!"

Linus Torvalds 40031da445 ACPI and power management updates for 3.12-rc1 
1) ACPI-based PCI hotplug (ACPIPHP) subsystem rework and introduction
     of Intel Thunderbolt support on systems that use ACPI for signalling
     Thunderbolt hotplug events.  This also should make ACPIPHP work in
     some cases in which it was known to have problems.  From
     Rafael J Wysocki, Mika Westerberg and Kirill A Shutemov.
 
  2) ACPI core code cleanups and dock station support cleanups from
     Jiang Liu and Rafael J Wysocki.
 
  3) Fixes for locking problems related to ACPI device hotplug from
     Rafael J Wysocki.
 
  4) ACPICA update to version 20130725 includig fixes, cleanups, support
     for more than 256 GPEs per GPE block and a change to make the ACPI
     PM Timer optional (we've seen systems without the PM Timer in the
     field already).  One of the fixes, related to the DeRefOf operator,
     is necessary to prevent some Windows 8 oriented AML from causing
     problems to happen.  From Bob Moore, Lv Zheng, and Jung-uk Kim.
 
  5) Removal of the old and long deprecated /proc/acpi/event interface
     and related driver changes from Thomas Renninger.
 
  6) ACPI and Xen changes to make the reduced hardware sleep work with
     the latter from Ben Guthro.
 
  7) ACPI video driver cleanups and a blacklist of systems that should
     not tell the BIOS that they are compatible with Windows 8 (or ACPI
     backlight and possibly other things will not work on them).  From
     Felipe Contreras.
 
  8) Assorted ACPI fixes and cleanups from Aaron Lu, Hanjun Guo,
     Kuppuswamy Sathyanarayanan, Lan Tianyu, Sachin Kamat, Tang Chen,
     Toshi Kani, and Wei Yongjun.
 
  9) cpufreq ondemand governor target frequency selection change to
     reduce oscillations between min and max frequencies (essentially,
     it causes the governor to choose target frequencies proportional
     to load) from Stratos Karafotis.
 
 10) cpufreq fixes allowing sysfs attributes file permissions to be
     preserved over suspend/resume cycles Srivatsa S Bhat.
 
 11) Removal of Device Tree parsing for CPU device nodes from multiple
     cpufreq drivers that required some changes related to
     of_get_cpu_node() to be made in a few architectures and in the
     driver core.  From Sudeep KarkadaNagesha.
 
 12) cpufreq core fixes and cleanups related to mutual exclusion and
     driver module references from Viresh Kumar, Lukasz Majewski and
     Rafael J Wysocki.
 
 13) Assorted cpufreq fixes and cleanups from Amit Daniel Kachhap,
     Bartlomiej Zolnierkiewicz, Hanjun Guo, Jingoo Han, Joseph Lo,
     Julia Lawall, Li Zhong, Mark Brown, Sascha Hauer, Stephen Boyd,
     Stratos Karafotis, and Viresh Kumar.

     Tuukka Tikkanen.
 
 16) Assorted cpuidle fixes and cleanups from Daniel Lezcano,
     Geert Uytterhoeven, Jingoo Han, Julia Lawall, Linus Walleij,
