         - a bugfix to pstore registration that makes it also work on
           non-Google systems
         - addition of new shipped Chromebooks (later models have more probing
           through ACPI so the need for these updates will be less over time).
         - A couple of minor coding style updates"

      Pull nouveau drm updates from Ben Skeggs:
       "Apologies for not getting this done in time for Dave's drm-next merge
        window.  As he mentioned, a pre-existing bug reared its head a lot
        more obviously after this lot of changes.  It took quite a bit of time
        to track it down.  In any case, Dave suggested I try my luck by
        sending directly to you this time.
      
        Overview:
      
         - more code for Tegra GK20A from NVIDIA - probing, reclockig
         - better fix for Kepler GPUs that have the graphics engine powered
           off on startup, method courtesy of info provided by NVIDIA
         - unhardcoding of a bunch of graphics engine setup on
           Fermi/Kepler/Maxwell, will hopefully solve some issues people have
           noticed on higher-end models
         - support for "Zero Bandwidth Clear" on Fermi/Kepler/Maxwell, needs
           userspace support in general, but some lucky apps will benefit
           automagically
         - reviewed/exposed the full object APIs to userspace (finally), gives
           it access to perfctrs, ZBC controls, various events.  More to come
           in the future.
         - various other fixes"

      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"

      Pull namespace updates from Eric Biederman:
       "This is a bunch of small changes built against 3.16-rc6.  The most
        significant change for users is the first patch which makes setns
        drmatically faster by removing unneded rcu handling.
      
        The next chunk of changes are so that "mount -o remount,.." will not
        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"
