      Pull device tree updates from Grant Likely:
       "The branch contains the following device tree changes the v3.17 merge
        window:
      
        Group changes to the device tree.  In preparation for adding device
        tree overlay support, OF_DYNAMIC is reworked so that a set of device
        tree changes can be prepared and applied to the tree all at once.
        OF_RECONFIG notifiers see the most significant change here so that
        users always get a consistent view of the tree.  Notifiers generation
        is moved from before a change to after it, and notifiers for a group
        of changes are emitted after the entire block of changes have been
        applied
      
        Automatic console selection from DT.  Console drivers can now use
        of_console_check() to see if the device node is specified as a console
        device.  If so then it gets added as a preferred console.  UART
        devices get this support automatically when uart_add_one_port() is
        called.
      
        DT unit tests no longer depend on pre-loaded data in the device tree.
        Data is loaded dynamically at the start of unit tests, and then
        unloaded again when the tests have completed.
      
        Also contains a few bugfixes for reserved regions and early memory
        setup"

       - Allow the thin target to paired with any size external origin; also
         allow thin snapshots to be larger than the external origin.
      
       - Add support for quickly loading a repetitive pattern into the

       - Use per-bio data in the dm-crypt target instead of always using a
         mempool for each allocation.  Required switching to kmalloc alignment

         to match the data block size -- this fixes an issue where mkfs.xfs

      Linus Torvalds authored
      Pull x86/apic updates from Thomas Gleixner:
       "This is a major overhaul to the x86 apic subsystem consisting of the
        following parts:
      
         - Remove obsolete APIC driver abstractions (David Rientjes)
      
         - Use the irqdomain facilities to dynamically allocate IRQs for
           IOAPICs.  This is a prerequisite to enable IOAPIC hotplug support,
           and it also frees up wasted vectors (Jiang Liu)
      
         - Misc fixlets.
      
        Despite the hickup in Ingos previous pull request - caused by the
        missing fixup for the suspend/resume issue reported by Borislav - I
        strongly recommend that this update finds its way into 3.17.  Some
        history for you:
      
        This is preparatory work for physical IOAPIC hotplug.  The first
        attempt to support this was done by Yinghai and I shot it down because
        it just added another layer of obscurity and complexity to the already
        existing mess without tackling the underlying shortcomings of the
        current implementation.
      
        After quite some on- and offlist discussions, I requested that the
        design of this functionality must use generic infrastructure, i.e.
        irq domains, which provide all the mechanisms to dynamically map linux
        interrupt numbers to physical interrupts.
      
        Jiang picked up the idea and did a great job of consolidating the
        existing interfaces to manage the x86 (IOAPIC) interrupt system by
        utilizing irq domains.
      
        The testing in tip, Linux-next and inside of Intel on various machines
        did not unearth any oddities until Borislav exposed it to one of his
        oddball machines.  The issue was resolved quickly, but unfortunately
        the fix fell through the cracks and did not hit the tip tree before
        Ingo sent the pull request.  Not entirely Ingos fault, I also assumed
        that the fix was already merged when Ingo asked me whether he could
        send it.
      
        Nevertheless this work has a proper design, has undergone several
        rounds of review and the final fallout after applying it to tip and
        integrating it into Linux-next has been more than moderate.  It's the
        ground work not only for IOAPIC hotplug, it will also allow us to move
        the lowlevel vector allocation into the irqdomain hierarchy, which
        will benefit other architectures as well.  Patches are posted already,
        but they are on hold for two weeks, see below.
      
        I really appreciate the competence and responsiveness Jiang has shown
        in course of this endavour.  So I'm sure that any fallout of this will
        be addressed in a timely manner.
      
        FYI, I'm vanishing for 2 weeks into my annual kids summer camp kitchen
        duty^Wvacation, while you folks are drooling at KS/LinuxCon :) But HPA
        will have a look at the hopefully zero fallout until I'm back"

      reiserfs: Fix use after free in journal teardown · 01777836
      Jan Kara authored
      If do_journal_release() races with do_journal_end() which requeues
      delayed works for transaction flushing, we can leave work items for
      flushing outstanding transactions queued while freeing them. That
      results in use after free and possible crash in run_timers_softirq().
      
      Fix the problem by not requeueing works if superblock is being shut down
      (MS_ACTIVE not set) and using cancel_delayed_work_sync() in
      do_journal_release().

      sparc64: Fix pcr_ops initialization and usage bugs. · 8bccf5b3
      David S. Miller authored
      Christopher reports that perf_event_print_debug() can crash in uniprocessor
      builds.  The crash is due to pcr_ops being NULL.
      
      This happens because pcr_arch_init() is only invoked by smp_cpus_done() which
      only executes in SMP builds.
      
      init_hw_perf_events() is closely intertwined with pcr_ops being setup properly,
      therefore:
      
      1) Call pcr_arch_init() early on from init_hw_perf_events(), instead of
         from smp_cpus_done().
      
      2) Do not hook up a PMU type if pcr_ops is NULL after pcr_arch_init().
      
      3) Move init_hw_perf_events to a later initcall so that it we will be
         sure to invoke pcr_arch_init() after all cpus are brought up.
      
      Finally, guard the one naked sequence of pcr_ops dereferences in
      __global_pmu_self() with an appropriate NULL check.

      sparc64: Do not disable interrupts in nmi_cpu_busy() · 58556104
      David S. Miller authored
      nmi_cpu_busy() is a SMP function call that just makes sure that all of the
      cpus are spinning using cpu cycles while the NMI test runs.
      
      It does not need to disable IRQs because we just care about NMIs executing
      which will even with 'normal' IRQs disabled.
      
      It is not legal to enable hard IRQs in a SMP cross call, in fact this bug
      triggers the BUG check in irq_work_run_list():
      
      	BUG_ON(!irqs_disabled());
      
      Because now irq_work_run() is invoked from the tail of
      generic_smp_call_function_single_interrupt().
