      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().

       "Stuff in here:
      
         - acct.c fixes and general rework of mnt_pin mechanism.  That allows
           to go for delayed-mntput stuff, which will permit mntput() on deep
           stack without worrying about stack overflows - fs shutdown will
           happen on shallow stack.  IOW, we can do Eric's umount-on-rmdir
           series without introducing tons of stack overflows on new mntput()
           call chains it introduces.
         - Bruce's d_splice_alias() patches
         - more Miklos' rename() stuff.
         - a couple of regression fixes (stable fodder, in the end of branch)
           and a fix for API idiocy in iov_iter.c.
      
        There definitely will be another pile, maybe even two.  I'd like to
        get Eric's series in this time, but even if we miss it, it'll go right
        in the beginning of for-next in the next cycle - the tricky part of
        prereqs is in this pile"

      fix copy_tree() regression · 12a5b529
      Al Viro authored
      Since 3.14 we had copy_tree() get the shadowing wrong - if we had one
      vfsmount shadowing another (i.e. if A is a slave of B, C is mounted
      on A/foo, then D got mounted on B/foo creating D' on A/foo shadowed
      by C), copy_tree() of A would make a copy of D' shadow the the copy of
      C, not the other way around.
      
      It's easy to fix, fortunately - just make sure that mount follows
      the one that shadows it in mnt_child as well as in mnt_hash, and when
      copy_tree() decides to attach a new mount, check if the last child
      it has added to the same parent should be shadowing the new one.
      And if it should, just use the same logics commit_tree() has - put the
      new mount into the hash and children lists right after the one that
      should shadow it.

      If DIO results in short write and sync write fails, we want to bugger off
      whether the DIO part has written anything or not; the logics on the return
      will take care of the right return value.

      Revert "proc: Point /proc/{mounts,net} at /proc/thread-self/{mounts,net} instead of /proc/self/{mounts,net}"
      
      This reverts commits 344470ca and e8132440.
      
      It turns out that the exact path in the symlink matters, if for somewhat
      unfortunate reasons: some apparmor configurations don't allow dhclient
      access to the per-thread /proc files.  As reported by Jörg Otte:
      
        audit: type=1400 audit(1407684227.003:28): apparmor="DENIED"
          operation="open" profile="/sbin/dhclient"
          name="/proc/1540/task/1540/net/dev" pid=1540 comm="dhclient"
          requested_mask="r" denied_mask="r" fsuid=0 ouid=0
      
      so we had better revert this for now.  We might be able to work around
      this in practice by only using the per-thread symlinks if the thread
      isn't the thread group leader, and if the namespaces differ between
      threads (which basically never happens).
      
      We'll see. In the meantime, the revert was made to be intentionally easy.

      Pull trace file read iterator fixes from Steven Rostedt:
       "This contains a fix for two long standing bugs.  Both of which are
        rarely ever hit, and requires the user to do something that users
        rarely do.  It took a few special test cases to even trigger this bug,
        and one of them was just one test in the process of finishing up as
        another one started.
      
        Both bugs have to do with the ring buffer iterator rb_iter_peek(), but
        one is more indirect than the other.
      
        The fist bug fix is simply an increase in the safety net loop counter.
        The counter makes sure that the rb_iter_peek() only iterates the
        number of times we expect it can, and no more.  Well, there was one
        way it could iterate one more than we expected, and that caused the
        ring buffer to shutdown with a nasty warning.  The fix was simply to
        up that counter by one.
      
        The other bug has to be with rb_iter_reset() (called by
        rb_iter_peek()).  This happens when a user reads both the trace_pipe
        and trace files.  The trace_pipe is a consuming read and does not use
        the ring buffer iterator, but the trace file is not a consuming read
        and does use the ring buffer iterator.  When the trace file is being
        read, if it detects that a consuming read occurred, it resets the
        iterator and starts over.  But the reset code that does this
        (rb_iter_reset()), checks if the reader_page is linked to the ring
        buffer or not, and will look into the ring buffer itself if it is not.
        This is wrong, as it should always try to read the reader page first.
        Not to mention, the code that looked into the ring buffer did it
        wrong, and used the header_page "read" offset to start reading on that
        page.  That offset is bogus for pages in the writable ring buffer, and
        was corrupting the iterator, and it would start returning bogus
        events"

        allow the user namespace root to drop flags on a mount set by the
        system wide root.  Aks this forces read-only mounts to stay read-only,
        no-dev mounts to stay no-dev, no-suid mounts to stay no-suid, no-exec
        mounts to stay no exec and it prevents unprivileged users from messing
        with a mounts atime settings.  I have included my test case as the
        last patch in this series so people performing backports can verify
        this change works correctly.
      
        The next change fixes a bug in NFS that was discovered while auditing
        nsproxy users for the first optimization.  Today you can oops the
        kernel by reading /proc/fs/nfsfs/{servers,volumes} if you are clever
        with pid namespaces.  I rebased and fixed the build of the
        !CONFIG_NFS_FS case yesterday when a build bot caught my typo.  Given
        that no one to my knowledge bases anything on my tree fixing the typo
        in place seems more responsible that requiring a typo-fix to be
        backported as well.
      
        The last change is a small semantic cleanup introducing
        /proc/thread-self and pointing /proc/mounts and /proc/net at it.  This
        prevents several kinds of problemantic corner cases.  It is a
        user-visible change so it has a minute chance of causing regressions
        so the change to /proc/mounts and /proc/net are individual one line
        commits that can be trivially reverted.  Unfortunately I lost and
        could not find the email of the original reporter so he is not
        credited.  From at least one perspective this change to /proc/net is a
        refgression fix to allow pthread /proc/net uses that were broken by
        the introduction of the network namespace"

       "Two small patches to fix a couple of build warnings in SELinux and
        NetLabel.  The patches are obvious enough that I don't think any
        additional explanation is necessary, but it basically boils down to
        the usual: I was stupid, and these patches fix some of the stupid.
      
        Both patches were posted earlier this week to the SELinux list, and
        that is where they sat as I didn't think there were noteworthy enough
        to go upstream at this point in time, but DaveM would rather see them
        upstream now so who am I to argue.  As the patches are both very
        small"

      We have another version of it implemented in SW, however, that version
      isn't serialised with normal PGRAPH operation and can possibly clobber

      This is the same method that's implemented by the NVIDIA binary driver.
