      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"

      Thomas Bogendoerfer authored
      The last line of PARISC machines (C8000, RP34x0, etc.) have a BMC for
      controlling temperature, fan speed and other stuff.  The BMC is
      connected via a special bus and listed in the firmware device tree.
      This change adds support for these BMCs to the IPMI driver.

      Jordan_Hargrave@Dell.com authored
      I'd submitted this about a year ago but it never made it upstream.
      
      The latest versions of the kernel drivers for ipmi can use ACPI to
      determine the type of BMC device used in the system.  The following
      patch adds a module alias so that udev will autoload the ipmi_si driver.

        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:

         - 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.

      Pull ext4 updates from Ted Ts'o:
       "New features for 3.12:
      
         - Added aggressive extent caching using the extent status tree.  This
           can actually decrease memory usage in read-mostly workloads since
           the information is much more compactly stored in the extent status
           tree than if we had to keep the extent tree metadata blocks in the
           buffer cache.  This also improves Asynchronous I/O since it is it
           makes much less likely that we need to do metadata I/O to lookup
           the extent tree information.

       "Changes are seen in a wide range of codes, mainly due to ASoC DAPM
        requirements; HD-audio shows a high peak in diffstat, it's just a
        removal of bunch of old static quirks.
      
        Some highlights:
      
         - HDPM: Updates for AIO/RayDAT support, TCO/sync support
      
         - RME96: Add PCM sync support
      
         - HD-audio:
      
           * A few HDMI/DP audio updates (CA assignment fix, stream switching
             fix, Intel DP device list support)
           * Device specific fixes (ASUS/CXT HP mic support, Thinkpad mic
             improvements, Chromebook fixes, STAC9228 Dell fixes)
           * Replace the all static quirks for AD codecs with the generic
             parser
           * WAKEEN support for handling irqs in the power saving mode
      
         - USB-audio: Clean up implicit fb handling and related codes
      
         - DAPM is now mandatory for ASoC CODEC drivers; all existing drivers
           have had some level of DAPM support added.  In addition, a lot of
           cleanups and improvements in DAPM.
      
         - Support for ASoC cross-platform compile test
      
         - New drivers and support for Analog Devices ADAU1702 and

      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.
      
         - 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 Laxman
           Dewangan.  This is used on the Tegra systems.
      
         - A major cleanup and modernization of the PFC (Super Hitachi and ARM
           SHmobile) pin controller and subdrivers.
      
         - Support for the A20 and A31 sunxi (AllWinner) SoCs.
      
         - A huge pile of fixes and cleanups: Axel Lin, Jingoo Han Dan
           Carpenter, Julia Lawall and Sachin Kamat did an excellent job here"

       "As a preparation for Andi Kleen's LTO patchset (link time
        optimizations using GCC's -flto which build time optimization has
        steadily increased in quality over the past few years and might
        eventually be usable for the kernel too) this tree includes a handful
        of preparatory patches that make function calling convention
        annotations consistent again:
      
         - Mark every function without arguments (or 64bit only) that is used
           by assembly code with asmlinkage()
      
         - Mark every function with parameters or variables that is used by
           assembly code as __visible.
      
        For the vanilla kernel this has documentation, consistency and
        debuggability advantages, for the time being"

      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.

                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!"

       "Main RCU changes this cycle were:
      
         - Full-system idle detection.  This is for use by Frederic
           Weisbecker's adaptive-ticks mechanism.  Its purpose is to allow the
           timekeeping CPU to shut off its tick when all other CPUs are idle.
      
         - Miscellaneous fixes.
      
         - Improved rcutorture test coverage.
      
         - Updated RCU documentation"

      direct-io: Handle O_(D)SYNC AIO · 02afc27f
      Christoph Hellwig authored
      Call generic_write_sync() from the deferred I/O completion handler if
      O_DSYNC is set for a write request.  Also make sure various callers
      don't call generic_write_sync if the direct I/O code returns
      -EIOCBQUEUED.
      
      Based on an earlier patch from Jan Kara <jack@suse.cz> with updates from
      Jeff Moyer <jmoyer@redhat.com> and Darrick J. Wong <darrick.wong@oracle.com>.

      direct-io: Implement generic deferred AIO completions · 7b7a8665
      Christoph Hellwig authored
      Add support to the core direct-io code to defer AIO completions to user
      context using a workqueue.  This replaces opencoded and less efficient
      code in XFS and ext4 (we save a memory allocation for each direct IO)
      and will be needed to properly support O_(D)SYNC for AIO.
      
      The communication between the filesystem and the direct I/O code requires
      a new buffer head flag, which is a bit ugly but not avoidable until the
      direct I/O code stops abusing the buffer_head structure for communicating
      with the filesystems.
      
      Currently this creates a per-superblock unbound workqueue for these
      completions, which is taken from an earlier patch by Jan Kara.  I'm
      not really convinced about this use and would prefer a "normal" global
      workqueue with a high concurrency limit, but this needs further discussion.
      
      JK: Fixed ext4 part, dynamic allocation of the workqueue.
