           allowing active and inactive DM tables to share dm_devs)

      Pull core block layer changes from Jens Axboe:
       "This is the core block IO pull request for 3.18.  Apart from the new
        and improved flush machinery for blk-mq, this is all mostly bug fixes
        and cleanups.
      
         - blk-mq timeout updates and fixes from Christoph.
      
         - Removal of REQ_END, also from Christoph.  We pass it through the
           ->queue_rq() hook for blk-mq instead, freeing up one of the request
           bits.  The space was overly tight on 32-bit, so Martin also killed
           REQ_KERNEL since it's no longer used.
      
         - blk integrity updates and fixes from Martin and Gu Zheng.
      
         - Update to the flush machinery for blk-mq from Ming Lei.  Now we
           have a per hardware context flush request, which both cleans up the
           code should scale better for flush intensive workloads on blk-mq.
      
         - Improve the error printing, from Rob Elliott.
      
         - Backing device improvements and cleanups from Tejun.
      
         - Fixup of a misplaced rq_complete() tracepoint from Hannes.
      
         - Make blk_get_request() return error pointers, fixing up issues
           where we NULL deref when a device goes bad or missing.  From Joe
           Lawrence.
      
         - Prep work for drastically reducing the memory consumption of dm
           devices from Junichi Nomura.  This allows creating clone bio sets
           without preallocating a lot of memory.
      
         - Fix a blk-mq hang on certain combinations of queue depths and
           hardware queues from me.
      
         - Limit memory consumption for blk-mq devices for crash dump
           scenarios and drivers that use crazy high depths (certain SCSI
           shared tag setups).  We now just use a single queue and limited
           depth for that"

      x86,kvm,vmx: Preserve CR4 across VM entry · d974baa3
      Andy Lutomirski authored
      CR4 isn't constant; at least the TSD and PCE bits can vary.
      
      TBH, treating CR0 and CR3 as constant scares me a bit, too, but it looks
      like it's correct.
      
      This adds a branch and a read from cr4 to each vm entry.  Because it is
      extremely likely that consecutive entries into the same vcpu will have
      the same host cr4 value, this fixes up the vmcs instead of restoring cr4
      after the fact.  A subsequent patch will add a kernel-wide cr4 shadow,
      reducing the overhead in the common case to just two memory reads and a
      branch.

      futex: Ensure get_futex_key_refs() always implies a barrier · 76835b0e
      Catalin Marinas authored
      Commit b0c29f79 (futexes: Avoid taking the hb->lock if there's
      nothing to wake up) changes the futex code to avoid taking a lock when
      there are no waiters. This code has been subsequently fixed in commit
      11d4616b (futex: revert back to the explicit waiter counting code).
      Both the original commit and the fix-up rely on get_futex_key_refs() to
      always imply a barrier.
      
      However, for private futexes, none of the cases in the switch statement
      of get_futex_key_refs() would be hit and the function completes without
      a memory barrier as required before checking the "waiters" in
      futex_wake() -> hb_waiters_pending(). The consequence is a race with a
      thread waiting on a futex on another CPU, allowing the waker thread to
      read "waiters == 0" while the waiter thread to have read "futex_val ==
      locked" (in kernel).
      
      Without this fix, the problem (user space deadlocks) can be seen with
      Android bionic's mutex implementation on an arm64 multi-cluster system.

      bna: fix skb->truesize underestimation · f2d9da1a
      Eric Dumazet authored
      skb->truesize is not meant to be tracking amount of used bytes
      in an skb, but amount of reserved/consumed bytes in memory.
      
      For instance, if we use a single byte in last page fragment,
      we have to account the full size of the fragment.
      
      skb->truesize can be very different from skb->len, that has
      a very specific safety purpose.

      dsa: Fix conversion from host device to mii bus · b184e497
      Guenter Roeck authored
      Commit b4d2394d ("dsa: Replace mii_bus with a generic host device")
      replaces mii_bus with a generic host_dev, and introduces
      dsa_host_dev_to_mii_bus() to support conversion from host_dev to mii_bus.
      However, in some cases it uses to_mii_bus to perform that conversion.
      Since host_dev is not the phy bus device but typically a platform device,
      this fails and results in a crash with the affected drivers.

      tipc: fix bug in bundled buffer reception · 643566d4
      Jon Paul Maloy authored
      In commit ec8a2e56 ("tipc: same receive
      code path for connection protocol and data messages") we omitted the
      the possiblilty that an arriving message extracted from a bundle buffer
      may be a multicast message. Such messages need to be to be delivered to
      the socket via a separate function, tipc_sk_mcast_rcv(). As a result,
      small multicast messages arriving as members of a bundle buffer will be
      silently dropped.
      
      This commit corrects the error by considering this case in the function
      tipc_link_bundle_rcv().

      ipv6: introduce tcp_v6_iif() · 870c3151
      Eric Dumazet authored
      Commit 971f10ec ("tcp: better TCP_SKB_CB layout to reduce cache line
      misses") added a regression for SO_BINDTODEVICE on IPv6.
      
      This is because we still use inet6_iif() which expects that IP6 control
      block is still at the beginning of skb->cb[]
      
      This patch adds tcp_v6_iif() helper and uses it where necessary.
      
      Because __inet6_lookup_skb() is used by TCP and DCCP, we add an iif
      parameter to it.

      Remove calling cancel_delayed_work_sync() for runtime suspend,
      because it would cause dead lock. Instead, return -EBUSY to
      avoid the device enters suspending if the net is running and
      the delayed work is pending or running. The delayed work would
      try to wake up the device later, so the suspending is not
      necessary.
