      Pull irq domain updates from Thomas Gleixner:
       "The real interesting irq updates:
      
         - Support for hierarchical irq domains:
      
           For complex interrupt routing scenarios where more than one
           interrupt related chip is involved we had no proper representation
           in the generic interrupt infrastructure so far.  That made people
           implement rather ugly constructs in their nested irq chip
           implementations.  The main offenders are x86 and arm/gic.
      
           To distangle that mess we have now hierarchical irqdomains which
           seperate the various interrupt chips and connect them via the
           hierarchical domains.  That keeps the domain specific details
           internal to the particular hierarchy level and removes the
           criss/cross referencing of chip internals.  The resulting hierarchy
           for a complex x86 system will look like this:
      
              vector          mapped: 74
                msi-0         mapped: 2
                dmar-ir-1     mapped: 69
                  ioapic-1    mapped: 4
                  ioapic-0    mapped: 20
                  pci-msi-2   mapped: 45
                dmar-ir-0     mapped: 3
                  ioapic-2    mapped: 1
                  pci-msi-1   mapped: 2
                htirq         mapped: 0
      
           Neither ioapic nor pci-msi know about the dmar interrupt remapping
           between themself and the vector domain.  If interrupt remapping is
           disabled ioapic and pci-msi become direct childs of the vector
           domain.
      
           In hindsight we should have done that years ago, but in hindsight
           we always know better :)
      
         - Support for generic MSI interrupt domain handling
      
           We have more and more non PCI related MSI interrupts, so providing
           a generic infrastructure for this is better than having all
           affected architectures implementing their own private hacks.
      
         - Support for PCI-MSI interrupt domain handling, based on the generic
           MSI support.
      
           This part carries the pci/msi branch from Bjorn Helgaas pci tree to
           avoid a massive conflict.  The PCI/MSI parts are acked by Bjorn.
      
        I have two more branches on top of this.  The full conversion of x86
        to hierarchical domains and a partial conversion of arm/gic"

      Pull scheduler updates from Ingo Molnar:
       "The main changes in this cycle are:
      
         - 'Nested Sleep Debugging', activated when CONFIG_DEBUG_ATOMIC_SLEEP=y.
      
           This instruments might_sleep() checks to catch places that nest
           blocking primitives - such as mutex usage in a wait loop.  Such
           bugs can result in hard to debug races/hangs.
      
           Another category of invalid nesting that this facility will detect
           is the calling of blocking functions from within schedule() ->
           sched_submit_work() -> blk_schedule_flush_plug().
      
           There's some potential for false positives (if secondary blocking
           primitives themselves are not ready yet for this facility), but the
           kernel will warn once about such bugs per bootup, so the warning
           isn't much of a nuisance.
      
           This feature comes with a number of fixes, for problems uncovered
           with it, so no messages are expected normally.
      
         - Another round of sched/numa optimizations and refinements, for
           CONFIG_NUMA_BALANCING=y.
      
         - Another round of sched/dl fixes and refinements.

      Pull perf events update from Ingo Molnar:
       "On the kernel side there's few changes, the one that stands out is
        PEBS machine state sampling support on x86, by Stephane Eranian.
      
        On the tooling side:
      
        User visible tooling changes:
      
         - Don't open the DWARF info multiple times, keeping instead a dwfl
           handle in struct dso, greatly speeding up 'perf report' on powerpc.
           (Sukadev Bhattiprolu)
      
         - Introduce PARSE_OPT_DISABLED option flag and use it to avoid
           showing undersired options in tools that provides frontends to
           'perf record', like sched, kvm, etc (Namhyung Kim)
      
         - Fallback to kallsyms when using the minimal 'ELF' loader (Arnaldo
           Carvalho de Melo)
      
         - Fix annotation with kcore (Adrian Hunter)
      
         - Support source line numbers in annotate using a hotkey (Andi Kleen)
      
         - Callchain improvements including:
           * Enable printing the srcline in the history
           * Make get_srcline fall back to sym+offset (Andi Kleen)
      
         - TUI hist_entry browser fixes, including showing missing overhead
           value for first level callchain.  Detected comparing the output of
           --stdio/--gui (that matched) with --tui, that had this problem.
           (Namhyung Kim)
      
         - Support handling complete branch stacks as histograms (Andi Kleen)
      
        Tooling infrastructure changes:
      
         - Prep work for supporting per-pkg and snapshot counters in 'perf
           stat' (Jiri Olsa)
      
         - 'perf stat' refactorings, moving stuff from it to evsel.c to use in
           per-pkg/snapshot format changes (Jiri Olsa)
      
         - Add per-pkg format file parsing (Matt Fleming)
      
         - Clean up libelf feature support code (Namhyung Kim)
      
         - Add gzip decompression support for kernel modules (Namhyung Kim)
      
         - More prep patches for Intel PT, including a a thread stack and more
           stuff made available via the database export mechanism (Adrian
           Hunter)
      
         - More Intel PT work, including a facility to export sample data
           (comms, threads, symbol names, etc) in a database friendly way,
           with an script to use this to create a postgresql database.
           (Adrian Hunter)
      
         - Make sure that thread->mg->machine points to the machine where the
           thread exists (it was being set only for the kmaps kernel modules
           case, do it as well for the mmaps) and use it to shorten function
           signatures (Arnaldo Carvalho de Melo)

      Pull asm-generic asm/io.h rewrite from Arnd Bergmann:
       "While there normally is no reason to have a pull request for
        asm-generic but have all changes get merged through whichever tree
        needs them, I do have a series for 3.19.
      
        There are two sets of patches that change significant portions of
        asm/io.h, and this branch contains both in order to resolve the
        conflicts:
      
         - Will Deacon has done a set of patches to ensure that all
           architectures define {read,write}{b,w,l,q}_relaxed() functions or
           get them by including asm-generic/io.h.
      
           These functions are commonly used on ARM specific drivers to avoid
           expensive L2 cache synchronization implied by the normal
           {read,write}{b,w,l,q}, but we need to define them on all
           architectures in order to share the drivers across architectures
           and to enable CONFIG_COMPILE_TEST configurations for them
      
         - Thierry Reding has done an unrelated set of patches that extends
           the asm-generic/io.h file to the degree necessary to make it useful
           on ARM64 and potentially other architectures"

      Pull ARM SoC/OMAP GPMC driver cleanup and move from Arnd Bergmann:
       "The GPMC driver has traditionally been considered a part of the OMAP

        With this cleanup, it has finally come to the point where it makes
        sense to move it out of arch/arm into drivers/memory, where we already
        have other drivers for similar hardware.  The cleanups are still
        ongoing, with the goal of eventually having a standalone driver that
        does not require an interface to architecture code.

      Pull ARM SoC DT updates from Arnd Bergmann:
       "The DT branch adds a lot of new stuff for additional SoC and board
        support.  The branch is the largest one and contains 513 out of the
        total 972 non-merge arm-soc changesets for 3.19.
      
        Most of the changes are about enabling additional on-chip devices for
        existing machines, but there are also an unusual number of new SoC
        types being added this time:
      
         - AMLogic Meson8

         - STMicroelectronics STiH410
         - Samsung Exynos4415
      
        The level of support for the above differs widely, some are just stubs
        with nothing more than CPU, memory and a UART, but others are fairly
        complete.  As usual, these get extended over time.
      
        There are also many new boards getting added, this is the list of
