      Pull ARM SoC fixes from Olof Johansson:
       "This is a batch of fixes for arm-soc platforms, most of it is for OMAP
        but there are others too (i.MX, Tegra, ep93xx).  Fixes warnings, some
        broken platforms and drivers, etc.  A bit all over the map really."
      
      There was some concern about commit 68136b10 ("RM: sunxi: Change device
      tree naming scheme for sunxi"), but Tony says:
       "Looks like that's trivial to fix as needed, no need to rebuild the
        branch to fix that AFAIK.
      
        The fix can be done once Olof is available online again.
      
        Linus, I suggest that you go ahead and pull this if there are no other
        issues with this branch."

      sched: numa: ksm: fix oops in task_numa_placment() · 2832bc19
      Hugh Dickins authored
      task_numa_placement() oopsed on NULL p->mm when task_numa_fault() got
      called in the handling of break_ksm() for ksmd.  That might be a
      peculiar case, which perhaps KSM could takes steps to avoid? but it's
      more robust if task_numa_placement() allows for such a possibility.

      mm: do not sleep in balance_pgdat if there's no i/o congestion · cda73a10
      Zlatko Calusic authored
      On a 4GB RAM machine, where Normal zone is much smaller than DMA32 zone,
      the Normal zone gets fragmented in time.  This requires relatively more
      pressure in balance_pgdat to get the zone above the required watermark.
      Unfortunately, the congestion_wait() call in there slows it down for a
      completely wrong reason, expecting that there's a lot of
      writeback/swapout, even when there's none (much more common).  After a
      few days, when fragmentation progresses, this flawed logic translates to
      a very high CPU iowait times, even though there's no I/O congestion at
      all.  If THP is enabled, the problem occurs sooner, but I was able to
      see it even on !THP kernels, just by giving it a bit more time to occur.
      
      The proper way to deal with this is to not wait, unless there's
      congestion.  Thanks to Mel Gorman, we already have the function that
      perfectly fits the job.  The patch was tested on a machine which nicely
      revealed the problem after only 1 day of uptime, and it's been working
      great.

      dma-buf: remove fallback for !CONFIG_DMA_SHARED_BUFFER · ada65c74
      Maarten Lankhorst authored
      Documentation says that code requiring dma-buf should add it to
      select, so inline fallbacks are not going to be used. A link error
      will make it obvious what went wrong, instead of silently doing
      nothing at runtime.

      dma-buf: might_sleep() in dma_buf_unmap_attachment() · b6fa0cd6
      Rob Clark authored
      We never really clarified if unmap could be done in atomic context.
      But since mapping might require sleeping, this implies mutex in use
      to synchronize mapping/unmapping, so unmap could sleep as well.  Add
      a might_sleep() to clarify this.
