      Pull nvdimm fixes from Dan Williams:
       "A small crop of lockdep, sleeping while atomic, and other fixes /
        band-aids in advance of the full-blown reworks targeting the next
        merge window. The largest change here is "libnvdimm: fix blk free
        space accounting" which deletes a pile of buggy code that better
        testing would have caught before merging. The next change that is
        borderline too big for a late rc is switching the device-dax locking
        from rcu to srcu, I couldn't think of a smaller way to make that fix.
      
        The __copy_user_nocache fix will have a full replacement in 4.12 to
        move those pmem special case considerations into the pmem driver. The
        "libnvdimm: band aid btt vs clear poison locking" commit admits that
        our error clearing support for btt went in broken, so we just disable
        it in 4.11 and -stable. A replacement / full fix is in the pipeline
        for 4.12
      
        Some of these would have been caught earlier had DEBUG_ATOMIC_SLEEP
        been enabled on my development station. I wonder if we should have:
      
            config DEBUG_ATOMIC_SLEEP
              default PROVE_LOCKING
      
        ...since I mistakenly thought I got both with PROVE_LOCKING=y.
      
        These have received a build success notification from the 0day robot,
        and some have appeared in a -next release with no reported issues"

      Pull SCSI fixes from James Bottomley:
       "This is seven small fixes which are all for user visible issues that
        fortunately only occur in rare circumstances.
      
        The most serious is the sr one in which QEMU can cause us to read
        beyond the end of a buffer (I don't think it's exploitable, but just
        in case).
      
        The next is the sd capacity fix which means all non 512 byte sector
        drives greater than 2TB fail to be correctly sized.
      
        The rest are either in new drivers (qedf) or on error legs"
