       "Famouse last words: "final pull request" :-)
        I'm sending this because Jason Wang's fixes are pretty important
         1) Add missing per-cpu stats initialization to ip6_vti.  Otherwise
            lockdep spits out a call trace.  From Li RongQing.
         2) Fix NULL oops in wireless hwsim, from Javier Lopez
         3) TIPC deferred packet queue unlink must NULL out skb->next to avoid
            crashes.  From Erik Hugne
         4) Fix access to uninitialized buffer in nf_nat netfilter code, from
            Daniel Borkmann
         5) Fix lifetime of ipv6 loopback and SIT tunnel addresses, otherwise
            they basically timeout immediately.  From Hannes Frederic Sowa
         6) Fix DMA unmapping of TSO packets in bnx2x driver, from Michal
         7) Do not allow L2 forwarding offload via macvtap device, the way
            things are now it will not end up being forwaded at all.  From
            Jason Wang
         8) Fix transmit queue selection via ndo_dfwd_start_xmit(), fixing
            things like applying NETIF_F_LLTX to the wrong device (!!) and
            eliding the proper transmit watchdog handling

      It can be a problem when a pattern is loaded via the firmware interface.
      LP55xx common driver has already locked the mutex in 'lp55xx_firmware_loaded()'.
      So it should be deleted.
      On the other hand, locks are required in store_engine_load()
      on updating program memory.

      net: core: explicitly select a txq before doing l2 forwarding · f663dd9a
      Jason Wang authored
      Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The
      will cause several issues:
      - NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan
        instead of lower device which misses the necessary txq synchronization for
        lower device such as txq stopping or frozen required by dev watchdog or
        control path.
      - dev_hard_start_xmit() was called with NULL txq which bypasses the net device
      - dev_hard_start_xmit() does not check txq everywhere which will lead a crash
        when tso is disabled for lower device.
      Fix this by explicitly introducing a new param for .ndo_select_queue() for just
      selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also
      extended to accept this parameter and dev_queue_xmit_accel() was used to do l2
      forwarding transmission.
      With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need
      to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep
      a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of
      dev_queue_xmit() to do the transmission.
      In the future, it was also required for macvtap l2 forwarding support since it
      provides a necessary synchronization method.

      bnx2x: fix DMA unmapping of TSO split BDs · 95e92fd4

      bnx2x triggers warnings with CONFIG_DMA_API_DEBUG=y:

        [unmap size=66 bytes]
      The reason is that bnx2x splits a TSO BD into two BDs (headers + data)
      using one DMA mapping for both, but it uses only the length of the first
      BD when unmapping.
      This patch fixes the bug by unmapping the whole length of the two BDs.

      ipv6: add link-local, sit and loopback address with INFINITY_LIFE_TIME · 07edd741
      Hannes Frederic Sowa authored
      In the past the IFA_PERMANENT flag indicated, that the valid and preferred
      lifetime where ignored. Since change fad8da3e
       ("ipv6 addrconf: fix
      preferred lifetime state-changing behavior while valid_lft is infinity")
      we honour at least the preferred lifetime on those addresses. As such
      the valid lifetime gets recalculated and updated to 0.
      If loopback address is added manually this problem does not occur.
      Also if NetworkManager manages IPv6, those addresses will get added via
      inet6_rtm_newaddr and thus will have a correct lifetime, too.

      Revert "intel_idle: mark states tables with __initdata tag" · ba0dc81e
      Jiang Liu authored
      This reverts commit 9d046ccb.
      Commit 9d046ccb marks all state tables with __initdata, but
      the state table may be accessed when doing CPU online, which then
      causing system crash as below:

      parisc: Ensure full cache coherency for kmap/kunmap · f8dae006
      John David Anglin authored
      Helge Deller noted a few weeks ago problems with the AIO support on
      parisc. This change is the result of numerous iterations on how best to
      deal with this problem.
      The solution adopted here is to provide full cache coherency in a
      uniform manner on all parisc systems. This involves calling
      flush_dcache_page() on kmap operations and flush_kernel_dcache_page() on
      kunmap operations. As a result, the copy_user_page() and
      clear_user_page() functions can be removed and the overall code is
      The change ensures that both userspace and kernel aliases to a mapped
      page are invalidated and flushed. This is necessary for the correct
      operation of PA8800 and PA8900 based systems which do not support
      inequivalent aliases.
      With this change, I have observed no cache related issues on c8000 and
      rp3440. It is now possible for example to do kernel builds with "-j64"
      on four way systems.
      On systems using XFS file systems, the patch recently posted by Mikulas
      Patocka to "fix crash using XFS on loopback" is needed to avoid a hang
      caused by an uninitialized lock passed to flush_dcache_page() in the
      page struct.
