       Highlights:
      - follow-up refactoring after the shared dpll rework that landed in 3.11
      - oddball prep cleanups from Ben for ppgtt
      - encoder->get_config state tracking infrastructure from Jesse
      - used by the experimental fastboot support from Jesse (disabled by
        default)
      - make the error state file official and add it to our sysfs interface
        (Mika)
      - drm_mm prep changes from Ben, prepares to embedd the drm_mm_node (which
        will be used by the vma rework later on)
      - interrupt handling rework, follow up cleanups to the VECS enabling, hpd
        storm handling and fifo underrun reporting.
      - Big pile of smaller cleanups, code improvements and related stuff.

      Pull driver core patches from Greg KH:
       "Here are some driver core patches for 3.11-rc2.  They aren't really
        bugfixes, but a bunch of new helper macros for drivers to properly
        create attribute groups, which drivers and subsystems need to fix up a
        ton of race issues with incorrectly creating sysfs files (binary and
        normal) after userspace has been told that the device is present.
      
        Also here is the ability to create binary files as attribute groups,
        to solve that race condition, which was impossible to do before this,
        so that's my fault the drivers were broken.
      
        The majority of the .c changes is indenting and moving code around a
        bit.  It affects no existing code, but allows the large backlog of 70+
        patches that I already have created to start flowing into the
        different subtrees, instead of having to live in my driver-core tree,
        causing merge nightmares in linux-next for the next few months.
      
        These were finalized too late for the -rc1 merge window, which is why
        they were didn't make that pull request, testing and review from
        others didn't happen until a few weeks ago, and then there's the whole
        distraction of the past few days, which prevented these from getting
        to you sooner, sorry about that.
      
        Oh, and there's a bugfix for the documentation build warning in here
        as well.  All of these have been in linux-next this week, with no
        reported problems"

      Pull phase two of __cpuinit removal from Paul Gortmaker:
       "With the __cpuinit infrastructure removed earlier, this group of
        commits only removes the function/data tagging that was done with the
        various (now no-op) __cpuinit related prefixes.
      
        Now that the dust has settled with yesterday's v3.11-rc1, there
        hopefully shouldn't be any new users leaking back in tree, but I think
        we can leave the harmless no-op stubs there for a release as a
        courtesy to those who still have out of tree stuff and weren't paying
        attention.
      
        Although the commits are against the recent tag to allow for minor
        context refreshes for things like yesterday's v3.11-rc1~ slab content,
        the patches have been largely unchanged for weeks, aside from such
        trivial updates.
      
        For detail junkies, the largely boring and mostly irrelevant history
        of the patches can be viewed at:
      
          http://git.kernel.org/cgit/linux/kernel/git/paulg/cpuinit-delete.git
      
        If nothing else, I guess it does at least demonstrate the level of
        involvement required to shepherd such a treewide change to completion.
      
        This is the same repository of patches that has been applied to the
        end of the daily linux-next branches for the past several weeks"

      md/raid1: fix bio handling problems in process_checks() · 30bc9b53
      NeilBrown authored
      Recent change to use bio_copy_data() in raid1 when repairing
      an array is faulty.
      
      The underlying may have changed the bio in various ways using
      bio_advance and these need to be undone not just for the 'sbio' which
      is being copied to, but also the 'pbio' (primary) which is being
      copied from.
      
      So perform the reset on all bios that were read from and do it early.
      
      This also ensure that the sbio->bi_io_vec[j].bv_len passed to
      memcmp is correct.
      
      This fixes a crash during a 'check' of a RAID1 array.  The crash was
      introduced in 3.10 so this is suitable for 3.10-stable.

      md: Remove recent change which allows devices to skip recovery. · 5024c298
      NeilBrown authored
      commit 7ceb17e8
          md: Allow devices to be re-added to a read-only array.
      
      allowed a bit more than just that.  It also allows devices to be added
      to a read-write array and to end up skipping recovery.
      
      This patch removes the offending piece of code pending a rewrite for a
      subsequent release.
      
      More specifically:
       If the array has a bitmap, then the device will still need a bitmap
       based resync ('saved_raid_disk' is set under different conditions
       is a bitmap is present).
       If the array doesn't have a bitmap, then this is correct as long as
       nothing has been written to the array since the metadata was checked
       by ->validate_super.  However there is no locking to ensure that there
       was no write.
      
      Bug was introduced in 3.10 and causes data corruption so
      patch is suitable for 3.10-stable.

      md/raid10: fix two problems with RAID10 resync. · 7bb23c49
      NeilBrown authored
      1/ When an different between blocks is found, data is copied from
         one bio to the other.  However bv_len is used as the length to
         copy and this could be zero.  So use r10_bio->sectors to calculate
         length instead.
         Using bv_len was probably always a bit dubious, but the introduction
         of bio_advance made it much more likely to be a problem.
      
      2/ When preparing some blocks for sync, we don't set BIO_UPTODATE
         except on bios that we schedule for a read.  This ensures that
         missing/failed devices don't confuse the loop at the top of
         sync_request write.
         Commit 8be185f2 "raid10: Use bio_reset()"
         removed a loop which set BIO_UPTDATE on all appropriate bios.
         So we need to re-add that flag.
      
      These bugs were introduced in 3.10, so this patch is suitable for
      3.10-stable, and can remove a potential for data corruption.

      One feature latecomer, I've forgotten to merge the patch to reeanble the
      Haswell power well feature now that the audio interaction is fixed up.
      Since that was the only unfixed issue with it I've figured I could throw
      it in a bit late, and it's trivial to revert in case I'm wrong.
      
      Otherwise all bug/regression fixes:
      - Fix status page reinit after gpu hangs, spotted by more paranoid igt
        checks.
      - Fix object list walking fumble regression in the shrinker (only the
        counting part, the actual shrinking code was correct so no Oops
        potential), from Xiong Zhang.
      - Fix DP 1.2 bw limits (Imre).
      - Restore legacy forcewake on ivb, too many broken biosen out there. We
        dump a warn though that recent userspace might fall over with that
        config (Guenter Roeck).
      - Patch up the gen2 cs tlb w/a.
      - Improve the fence coherency w/a now that we have a better understanding
        what's going on. The removed wbinvd+ipi should make -rt folks happy. Big
        thanks to Jon Bloomfield for figuring this out, patches from Chris.
      - Fix write-read race when switching ring (Chris). Spotted with code
        inspection, but now we also have an igt for it.
      
      There's an ugly regression we're still working on introduced between
      3.10-rc7 and 3.10.0. Unfortunately we can't just revert the offender since
      that one fixes another regression :( I've asked Steven to include my
      -fixes branch into linux-next to prevent such fallout in the future,
      hopefully.

      x86: Make sure IDT is page aligned · 4df05f36
      Kees Cook authored
      Since the IDT is referenced from a fixmap, make sure it is page aligned.
      Merge with 32-bit one, since it was already aligned to deal with F00F
      bug. Since bss is cleared before IDT setup, it can live there. This also
      moves the other *_idt_table variables into common locations.
      
      This avoids the risk of the IDT ever being moved in the bss and having
      the mapping be offset, resulting in calling incorrect handlers. In the
      current upstream kernel this is not a manifested bug, but heavily patched
      kernels (such as those using the PaX patch series) did encounter this bug.
      
      The tables other than idt_table technically do not need to be page
      aligned, at least not at the current time, but using a common
      declaration avoids mistakes.  On 64 bits the table is exactly one page
      long, anyway.

      sysfs: use file mode defines from stat.h · aa01aa3c
      Oliver Schinagl authored
      With the last patches stat.h was included to the header, and thus those
      permission defines should be used.

      driver core: add default groups to struct class · d05a6f96
      Greg Kroah-Hartman authored
      We should be using groups, not attribute lists, for classes to allow
      subdirectories, and soon, binary files.  Groups are just more flexible
      overall, so add them.
      
      The dev_attrs list will go away after all in-kernel users are converted
      to use dev_groups.

      driver core: Introduce device_create_groups · 39ef3112
      Guenter Roeck authored
      device_create_groups lets callers create devices as well as associated
      sysfs attributes with a single call. This avoids race conditions seen
      if sysfs attributes on new devices are created later.
