      Pull embedded i2c changes from Wolfram Sang:
       "Changes for the "embedded" part of the I2C subsystem:
      
         - lots of devicetree conversions of drivers (and preparations for
           that)
         - big cleanups for drivers for OMAP, Tegra, Nomadik, Blackfin
         - Rafael's struct dev_pm_ops conversion patches for I2C
         - usual driver cleanups and fixes
      
        All patches have been in linux-next for an apropriate time and all
        patches touching files outside of i2c-folders should have proper acks
        from the maintainers."

      Pull ext4 updates from Ted Ts'o:
       "The usual collection of bug fixes and optimizations.  Perhaps of
        greatest note is a speed up for parallel, non-allocating DIO writes,

        For bug fixes, we fix an incorrect overhead calculation which caused
        slightly incorrect results for df(1) and statfs(2).  We also fixed
        bugs in the metadata checksum feature."

      ====================
      These fixes are intended for the 3.6 stream.
      
      Hauke Mehrtens provides a pair of bcma fixes, one to fix a build
      regression on mips and another to correct a pair of missing iounmap
      calls.
      
      Thomas Huehn offers a mac80211_hwsim fix to avoid a possible
      use-after-free bug.

      tcp: perform DMA to userspace only if there is a task waiting for it · 59ea33a6
      Jiri Kosina authored
      Back in 2006, commit 1a2449a8
      
       ("[I/OAT]: TCP recv offload to I/OAT")
      added support for receive offloading to IOAT dma engine if available.
      
      The code in tcp_rcv_established() tries to perform early DMA copy if
      applicable. It however does so without checking whether the userspace
      task is actually expecting the data in the buffer.
      
      This is not a problem under normal circumstances, but there is a corner
      case where this doesn't work -- and that's when MSG_TRUNC flag to
      recvmsg() is used.
      
      If the IOAT dma engine is not used, the code properly checks whether
      there is a valid ucopy.task and the socket is owned by userspace, but
      misses the check in the dmaengine case.
      
      This problem can be observed in real trivially -- for example 'tbench' is a
      good reproducer, as it makes a heavy use of MSG_TRUNC. On systems utilizing
      IOAT, you will soon find tbench waiting indefinitely in sk_wait_data(), as they
      have been already early-copied in tcp_rcv_established() using dma engine.
      
      This patch introduces the same check we are performing in the simple
      iovec copy case to the IOAT case as well. It fixes the indefinite
      recvmsg(MSG_TRUNC) hangs.

      This reverts commit 5b3e7e6c
      
      .
      
      The problem that the original commit was attempting to fix can
      never happen in practice because validation is done one a per-flow
      basis rather than a per-packet basis.  Adding additional checks at
      runtime is unnecessary and inconsistent with the rest of the code.
