      Pull device mapper fixes from Mike Snitzer:
      
       - dm-cache memory allocation failure fix
       - fix DM's Kconfig identation
       - dm-snapshot metadata corruption fix for bug introduced in 3.14-rc1
       - important refcount < 0 fix for the DM persistent data library's space
         map metadata interface which fixes corruption reported by a few
         dm-thinp users
      
      and last but not least:
      
       - more extensive fixes than ideal for dm-thinp's data resize capability
         (which has had growing pain much like we've seen from -ENOSPC
         handling of filesystems that mature).
      
         The end result is dm-thinp now handles metadata operation failure and
         no data space error conditions much better than before.

      dm space map metadata: fix refcount decrement below 0 which caused corruption · cebc2de4
      Joe Thornber authored
      This has been a relatively long-standing issue that wasn't nailed down
      until Teng-Feng Yang's meticulous bug report to dm-devel on 3/7/2014,
      see: http://www.redhat.com/archives/dm-devel/2014-March/msg00021.html
      
      From that report:
        "When decreasing the reference count of a metadata block with its
        reference count equals 3, we will call dm_btree_remove() to remove
        this enrty from the B+tree which keeps the reference count info in
        metadata device.
      
        The B+tree will try to rebalance the entry of the child nodes in each
        node it traversed, and the rebalance process contains the following
        steps.
      
        (1) Finding the corresponding children in current node (shadow_current(s))
        (2) Shadow the children block (issue BOP_INC)
        (3) redistribute keys among children, and free children if necessary (issue BOP_DEC)
      
        Since the update of a metadata block's reference count could be
        recursive, we will stash these reference count update operations in
        smm->uncommitted and then process them in a FILO fashion.
      
        The problem is that step(3) could free the children which is created
        in step(2), so the BOP_DEC issued in step(3) will be carried out
        before the BOP_INC issued in step(2) since these BOPs will be
        processed in FILO fashion. Once the BOP_DEC from step(3) tries to
        decrease the reference count of newly shadow block, it will report
        failure for its reference equals 0 before decreasing. It looks like we
        can solve this issue by processing these BOPs in a FIFO fashion
        instead of FILO."
      
      Commit 5b564d80 ("dm space map: disallow decrementing a reference count
      below zero") changed the code to report an error for this temporary
      refcount decrement below zero.  So what was previously a harmless
      invalid refcount became a hard failure due to the new error path:
      
       device-mapper: space map common: unable to decrement a reference count below 0
       device-mapper: thin: 253:6: dm_thin_insert_block() failed: error = -22
       device-mapper: thin: 253:6: switching pool to read-only mode
      
      This bug is in dm persistent-data code that is common to the DM thin and
      cache targets.  So any users of those targets should apply this fix.
      
      Fix this by applying recursive space map operations in FIFO order rather
      than FILO.

      dm thin: fix noflush suspend IO queueing · 738211f7
      Joe Thornber authored
      i) by the time DM core calls the postsuspend hook the dm_noflush flag
      has been cleared.  So the old thin_postsuspend did nothing.  We need to
      use the presuspend hook instead.
      
      ii) There was a race between bios leaving DM core and arriving in the
      deferred queue.
      
      thin_presuspend now sets a 'requeue' flag causing all bios destined for
      that thin to be requeued back to DM core.  Then it requeues all held IO,
      and all IO on the deferred queue (destined for that thin).  Finally
      postsuspend clears the 'requeue' flag.

      dm thin: fix deadlock in __requeue_bio_list · 18adc577
      Joe Thornber authored
      The spin lock in requeue_io() was held for too long, allowing deadlock.
      Don't worry, due to other issues addressed in the following "dm thin:
      fix noflush suspend IO queueing" commit, this code was never called.
      
      Fix this by taking the spin lock for a much shorter period of time.

      dm thin: fix out of data space handling · 3e1a0699
      Joe Thornber authored
      Ideally a thin pool would never run out of data space; the low water
      mark would trigger userland to extend the pool before we completely run
      out of space.  However, many small random IOs to unprovisioned space can
      consume data space at an alarming rate.  Adjust your low water mark if
      you're frequently seeing "out-of-data-space" mode.
      
      Before this fix, if data space ran out the pool would be put in
      PM_READ_ONLY mode which also aborted the pool's current metadata
      transaction (data loss for any changes in the transaction).  This had a
      side-effect of needlessly compromising data consistency.  And retry of
      queued unserviceable bios, once the data pool was resized, could
      initiate changes to potentially inconsistent pool metadata.
      
      Now when the pool's data space is exhausted transition to a new pool
      mode (PM_OUT_OF_DATA_SPACE) that allows metadata to be changed but data
      may not be allocated.  This allows users to remove thin volumes or
      discard data to recover data space.
      
      The pool is no longer put in PM_READ_ONLY mode in response to the pool
      running out of data space.  And PM_READ_ONLY mode no longer aborts the
      pool's current metadata transaction.  Also, set_pool_mode() will now
      notify userspace when the pool mode is changed.

      dm thin: ensure user takes action to validate data and metadata consistency · 07f2b6e0
      Mike Snitzer authored
      If a thin metadata operation fails the current transaction will abort,
      whereby causing potential for IO layers up the stack (e.g. filesystems)
      to have data loss.  As such, set THIN_METADATA_NEEDS_CHECK_FLAG in the
      thin metadata's superblock which:
      1) requires the user verify the thin metadata is consistent (e.g. use
         thin_check, etc)
      2) suggests the user verify the thin data is consistent (e.g. use fsck)
      
      The only way to clear the superblock's THIN_METADATA_NEEDS_CHECK_FLAG is
      to run thin_repair.
      
      On metadata operation failure: abort current metadata transaction, set
      pool in read-only mode, and now set the needs_check flag.
      
      As part of this change, constraints are introduced or relaxed:
      * don't allow a pool to transition to write mode if needs_check is set
      * don't allow data or metadata space to be resized if needs_check is set
      * if a thin pool's metadata space is exhausted: the kernel will now
        force the user to take the pool offline for repair before the kernel
        will allow the metadata space to be extended.
      
      Also, update Documentation to include information about when the thin
      provisioning target commits metadata, how it handles metadata failures
      and running out of space.

      pinctrl: sunxi: use chained_irq_{enter, exit} for GIC compatibility · 905a5117
      Chen-Yu Tsai authored
      On tha Allwinner A20 SoC, the external interrupts on the pin controller
      device are connected to the GIC. Without chained_irq_{enter, exit},
      external GPIO interrupts, such as used by mmc core card detect, cause
      the system to hang.
      
      This issue was first encountered during my attempt to get out-of-band
      interrupts for WiFi on the Cubietruck working. With David's new series
      of sunci-mci using mmc slot-gpio for (GPIO interrupt based) card
      detection, removing the SD card also causes my Cubietruck to hang. This
      problem should extend to all Allwinner A20 based boards.
      
      With this fix, the system no longer hangs when I remove or insert the
      SD card. /proc/interrupts show that the interrupt has correctly fired.
      However the system still does not detect card removal/insertion. I
      believe this is another unrelated issue.

      c6x: fix build failure caused by cache.h · ae72758f
      Mark Salter authored
      A patch to linux/irqflags.h uncovered a problem with c6x asm/cache.h
      which causes a build failure:
      
      /arch/c6x/include/asm/cache.h:63:20: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘c6x_cache_init’
       extern void __init c6x_cache_init(void);
      
      The asm/cache.h was relying on linux/irqflags.h to pull in linux/init.h
      but the recent patch changed that. The c6x header should have included
      linux/init.h all along.

       4) Fix mis-checksumming in xen-netfront driver, ip_hdr() is not in the
          correct place when we invoke skb_checksum_setup().  From Wei Liu.
      
       5) TUN driver should not advertise HW vlan offload features in
          vlan_features.  Fix from Fernando Luis Vazquez Cao.
      
       6) IPV6_VTI needs to select NET_IPV_TUNNEL to avoid build errors, fix
          from Steffen Klassert.
      
       7) Add missing locking in xfrm_migrade_state_find(), we must hold the

          under ath_txq_lock().  Fix from Stanislaw Gruszka.
      
       9) Fix two bugs in TCP fastopen.  First respect the size argument given
          to tcp_sendmsg() in the fastopen path, and secondly prevent
          tcp_send_syn_data() from potentially using order-5 allocations.

      15) Overzealous return from neigh_periodic_work() causes reachability
          time to not be computed.  Fix from Duain Jiong.

      17) Fix VLAN tag stripping regression in BNA driver, from Ivan Vecera.
      
      18) Tail loss probe can calculate bogus RTTs due to missing packet
          marking on retransmit.  Fix from Yuchung Cheng.
      
      19) We cannot do skb_dst_drop() in iptunnel_pull_header() because
          multicast loopback detection in later code paths need access to
          skb_rtable().  Fix from Xin Long.
      
      20) The macvlan driver regresses in that it propagates lower device
          offload support disables into itself, causing severe slowdowns when
          running over a bridge.  Provide the software offloads always on
          macvlan devices to deal with this and the regression is gone.  From
          Vlad Yasevich.
