       "The lion share of this pull request are fixes for clk-related breakage
        caused by other changes during this merge window.  For some platforms
        the fix was as simple as selecting HAVE_CLK, for others like the
        Loongson 2 significant restructuring was required.
      
        The remainder are changes required to get the Lantiq code to work
        again."

      Linus Torvalds authored
      Pull ARM DMA engine updates from Russell King:
       "This looks scary at first glance, but what it is is:
         - a rework of the sa11x0 DMA engine driver merged during the previous
           cycle, to extract a common set of helper functions for DMA engine
           implementations.
         - conversion of amba-pl08x.c to use these helper functions.
         - addition of OMAP DMA engine driver (using these helper functions),
           and conversion of some of the OMAP DMA users to use DMA engine.
      
        Nothing in the helper functions is ARM specific, so I hope that other
        implementations can consolidate some of their code by making use of
        these helpers.
      
        This has been sitting in linux-next most of the merge cycle, and has
        been tested by several OMAP folk.  I've tested it on sa11x0 platforms,
        and given it my best shot on my broken platforms which have the
        amba-pl08x controller.
      
        The last point is the addition to feature-removal-schedule.txt, which
        will have a merge conflict.  Between myself and TI, we're planning to
        remove the old TI DMA implementation next year."

      block: add partition resize function to blkpg ioctl · c83f6bf9
      Vivek Goyal authored
      Add a new operation code (BLKPG_RESIZE_PARTITION) to the BLKPG ioctl that
      allows altering the size of an existing partition, even if it is currently
      in use.
      
      This patch converts hd_struct->nr_sects into sequence counter because
      One might extend a partition while IO is happening to it and update of
      nr_sects can be non-atomic on 32bit machines with 64bit sector_t. This
      can lead to issues like reading inconsistent size of a partition. Sequence
      counter have been used so that readers don't have to take bdev mutex lock
      as we call sector_in_part() very frequently.
      
      Now all the access to hd_struct->nr_sects should happen using sequence
      counter read/update helper functions part_nr_sects_read/part_nr_sects_write.
      There is one exception though, set_capacity()/get_capacity(). I think
      theoritically race should exist there too but this patch does not
      modify set_capacity()/get_capacity() due to sheer number of call sites
      and I am afraid that change might break something. I have left that as a
      TODO item. We can handle it later if need be. This patch does not introduce
      any new races as such w.r.t set_capacity()/get_capacity().

      Hi,
      
      I'm using the old-fashioned 'dump' backup tool, and I noticed that it spews the
      below warning as of 3.5-rc1 and later (3.4 is fine):

      Reproducing is easy, I can hit it on a KVM system with a very basic
      config (x86_64 make defconfig + enable the drivers needed). To hit it,
      just install dump (on debian/ubuntu, not sure what the package might be
      called on Fedora), and:
      
      dump -o -f /tmp/foo /
      
      You'll see the warning in dmesg once it forks off the I/O process and
      starts dumping filesystem contents.
      
      I bisected it down to the following commit:

          Currently ioc->nr_tasks is used to decide two things - whether an ioc
          is done issuing IOs and whether it's shared by multiple tasks.  This
          patch separate out the first into ioc->active_ref, which is acquired
          and released using {get|put}_io_context_active() respectively.
      
          This will be used to associate bio's with a given task.  This patch
          doesn't introduce any visible behavior change.

      It seems like the init of ioc->nr_tasks was removed in that patch,
      so it starts out at 0 instead of 1.
      
      Tejun, is the right thing here to add back the init, or should something else
      be done?
      
      The below patch removes the warning, but I haven't done any more extensive

      block: do not artificially constrain max_sectors for stacking drivers · fe86cdce
      Mike Snitzer authored
      blk_set_stacking_limits is intended to allow stacking drivers to build
      up the limits of the stacked device based on the underlying devices'
      limits.  But defaulting 'max_sectors' to BLK_DEF_MAX_SECTORS (1024)
      doesn't allow the stacking driver to inherit a max_sectors larger than
      1024 -- due to blk_stack_limits' use of min_not_zero.
      
      It is now clear that this artificial limit is getting in the way so
      change blk_set_stacking_limits's max_sectors to UINT_MAX (which allows
      stacking drivers like dm-multipath to inherit 'max_sectors' from the
      underlying paths).

      Daniel Mack authored
      uac_clock_source_is_valid() uses the control selector value to access
      the bmControls bitmap of the clock source unit. This is wrong, as
      control selector values start from 1, while the bitmap uses all
      available bits.
      
      In other words, "Clock Validity Control" is stored in D3..2, not D5..4
      of the clock selector unit's bmControls.

       "Round of refactoring and enhancements to irq_domain infrastructure.
        This series starts the process of simplifying irqdomain.  The ultimate
        goal is to merge LEGACY, LINEAR and TREE mappings into a single
        system, but had to back off from that after some last minute bugs.
        Instead it mainly reorganizes the code and ensures that the reverse
        map gets populated when the irq is mapped instead of the first time it
        is looked up.
      
        Merging of the irq_domain types is deferred to v3.7
      
        In other news, this series adds helpers for creating static mappings
        on a linear or tree mapping."
