      Pull ARM SoC i.MX DT changes from Olof Johansson:
       "This branch contains of devicetree changes for the Freescale i.MX
        platform.
      
        The base patch of the branch changes the format of the dts files to a
        slightly different format that makes it easier to do derivative board
        definitions, but it also introduces a lot of churn in the process
        since every line of the file is touched.
      
        On top of that are a handful of the regular changes; enabling more
        boards as DT-based instead of legacy board files (mx25pdk), enabling
        another driver for devicetree and thus adding bindings (onewire), etc.
      
        I'm not happy about the churn, and will likely not take it for other
        platforms in the future."

      Pull nfsd changes from J Bruce Fields:
       "Miscellaneous bugfixes, plus:
      
         - An overhaul of the DRC cache by Jeff Layton.  The main effect is
           just to make it larger.  This decreases the chances of intermittent
           errors especially in the UDP case.  But we'll need to watch for any
           reports of performance regressions.
      
         - Containerized nfsd: with some limitations, we now support
           per-container nfs-service, thanks to extensive work from Stanislav
           Kinsbursky over the last year."
      
      Some notes about conflicts, since there were *two* non-data semantic
      conflicts here:
      
       - idr_remove_all() had been added by a memory leak fix, but has since
         become deprecated since idr_destroy() does it for us now.
      
       - xs_local_connect() had been added by this branch to make AF_LOCAL
         connections be synchronous, but in the meantime Trond had changed the
         calling convention in order to avoid a RCU dereference.
      
      There were a couple of more obvious actual source-level conflicts due to
      the hlist traversal changes and one just due to code changes next to
      each other, but those were trivial.

      Pull Ceph updates from Sage Weil:
       "A few groups of patches here.  Alex has been hard at work improving
        the RBD code, layout groundwork for understanding the new formats and
        doing layering.  Most of the infrastructure is now in place for the
        final bits that will come with the next window.
      
        There are a few changes to the data layout.  Jim Schutt's patch fixes
        some non-ideal CRUSH behavior, and a set of patches from me updates
        the client to speak a newer version of the protocol and implement an
        improved hashing strategy across storage nodes (when the server side
        supports it too).
      
        A pair of patches from Sam Lang fix the atomicity of open+create
        operations.  Several patches from Yan, Zheng fix various mds/client
        issues that turned up during multi-mds torture tests.
      
        A final set of patches expose file layouts via virtual xattrs, and
        allow the policies to be set on directories via xattrs as well
        (avoiding the awkward ioctl interface and providing a consistent
        interface for both kernel mount and ceph-fuse users)."

      SUNRPC: make AF_LOCAL connect synchronous · dc107402
      J. Bruce Fields authored
      It doesn't appear that anyone actually needs to connect asynchronously.
      
      Also, using a workqueue for the connect means we lose the namespace
      information from the original process.  This is a problem since there's

      hlist: drop the node parameter from iterators · b67bfe0d
      Sasha Levin authored
      I'm not sure why, but the hlist for each entry iterators were conceived
      
              list_for_each_entry(pos, head, member)
      
      The hlist ones were greedy and wanted an extra parameter:
      
              hlist_for_each_entry(tpos, pos, head, member)
      
      Why did they need an extra pos parameter? I'm not quite sure. Not only
      they don't really need it, it also prevents the iterator from looking
      exactly like the list iterator, which is unfortunate.
      
      Besides the semantic patch, there was some manual work required:
      
       - Fix up the actual hlist iterators in linux/list.h
       - Fix up the declaration of other iterators based on the hlist ones.
       - A very small amount of places were using the 'node' parameter, this
       was modified to use 'obj->member' instead.
       - Coccinelle didn't handle the hlist_for_each_entry_safe iterator
       properly, so those had to be fixed up manually.
      
      The semantic patch which is mostly the work of Peter Senna Tschudin is here:

      kcmp: make it depend on CHECKPOINT_RESTORE · 1e142b29
      Cyrill Gorcunov authored
      Since kcmp syscall has been implemented (initially on x86 architecture) a
      number of other archs wire it up as well: xtensa, sparc, sh, s390, mips,
      microblaze, m68k (not taking into account those who uses
      <asm-generic/unistd.h> for syscall numbers definitions).
      
      But the Makefile, which turns kcmp.o generation on still depends on former
      config-x86.  Thus get rid of this limitation and make kcmp.o depend on
      CHECKPOINT_RESTORE option.

      Using prandom_bytes() is enough.  Because this data is only used

      Alex Elder authored
      I just fixed this in "drivers/block/rbd.c" and I noticed that
      "drivers/block/nbd.c" has the same problem.  Fix a warning issued by
      sparse by adding some lockdep annotations to indicate the queue lock gets
      dropped (because it's held when do_nbd_request() is called) and
      re-acquired within the function.

      nbd: update documentation and link to mailinglist · 5e4b269b
      Wouter Verhelst authored
      Documentation/blockdev/nbd.txt contained some documentation which was
      horribly outdated and probably still dates from the original patch that
      added NBD support to the kernel.
      
      This patch removes the useless and outdated bits.  The tools on nbd.sf.net
      are fully documented in manpages, which is where documentation for the
      non-kernel bits should live.
      
      Additionally, add a reference to the MAINTAINERS file for the nbd-general
      mailinglist that is used for discussion of the userland tools and the
      kernel module already.

      nbd: fsync and kill block device on shutdown · 3a2d63f8
      Paolo Bonzini authored
      There are two problems with shutdown in the NBD driver.
      
      1: Receiving the NBD_DISCONNECT ioctl does not sync the filesystem.
      
         This patch adds the sync operation into __nbd_ioctl()'s
         NBD_DISCONNECT handler.  This is useful because BLKFLSBUF is restricted
         to processes that have CAP_SYS_ADMIN, and the NBD client may not
         possess it (fsync of the block device does not sync the filesystem,
         either).
      
      2: Once we clear the socket we have no guarantee that later reads will
         come from the same backing storage.
      
         The patch adds calls to kill_bdev() in __nbd_ioctl()'s socket
         clearing code so the page cache is cleaned, lest reads that hit on the
         page cache will return stale data from the previously-accessible disk.
      
      Example:
      
          # qemu-nbd -r -c/dev/nbd0 /dev/sr0
          # file -s /dev/nbd0
          /dev/stdin: # UDF filesystem data (version 1.5) etc.
          # qemu-nbd -d /dev/nbd0
          # qemu-nbd -r -c/dev/nbd0 /dev/sda
          # file -s /dev/nbd0
          /dev/stdin: # UDF filesystem data (version 1.5) etc.
      
      While /dev/sda has:
      
          # file -s /dev/sda
          /dev/sda: x86 boot sector; etc.

      nbd: support FLUSH requests · 75f187ab
      Alex Bligh authored
      Currently, the NBD device does not accept flush requests from the Linux
      block layer.  If the NBD server opened the target with neither O_SYNC nor
      O_DSYNC, however, the device will be effectively backed by a writeback
      cache.  Without issuing flushes properly, operation of the NBD device will
      not be safe against power losses.
      
      The NBD protocol has support for both a cache flush command and a FUA
      command flag; the server will also pass a flag to note its support for
      these features.  This patch adds support for the cache flush command and
      flag.  In the kernel, we receive the flags via the NBD_SET_FLAGS ioctl,
      and map NBD_FLAG_SEND_FLUSH to the argument of blk_queue_flush.  When the
      flag is active the block layer will send REQ_FLUSH requests, which we
      translate to NBD_CMD_FLUSH commands.
      
      FUA support is not included in this patch because all free software
      servers implement it with a full fdatasync; thus it has no advantage over
      supporting flush only.  Because I [Paolo] cannot really benchmark it in a
      realistic scenario, I cannot tell if it is a good idea or not.  It is also
      not clear if it is valid for an NBD server to support FUA but not flush.
      The Linux block layer gives a warning for this combination, the NBD
      protocol documentation says nothing about it.
      
      The patch also fixes a small problem in the handling of flags: nbd->flags
      must be cleared at the end of NBD_DO_IT, but the driver was not doing
      that.  The bug manifests itself as follows.  Suppose you two different
      client/server pairs to start the NBD device.  Suppose also that the first
      client supports NBD_SET_FLAGS, and the first server sends
      NBD_FLAG_SEND_FLUSH; the second pair instead does neither of these two
      things.  Before this patch, the second invocation of NBD_DO_IT will use a
      stale value of nbd->flags, and the second server will issue an error every
      time it receives an NBD_CMD_FLUSH command.
      
      This bug is pre-existing, but it becomes much more important after this
      patch; flush failures make the device pretty much unusable, unlike
