      be2net: dma_sync each RX frag before passing it to the stack · e50287be
      Sathya Perla authored
      The driver currently maps a page for DMA, divides the page into multiple
      frags and posts them to the HW. It un-maps the page after data is received
      on all the frags of the page. This scheme doesn't work when bounce buffers
      are used for DMA (swiotlb=force kernel param).
      This patch fixes this problem by calling dma_sync_single_for_cpu() for each
      frag (excepting the last one) so that the data is copied from the bounce
      buffers. The page is un-mapped only when DMA finishes on the last frag of
      the page.
      (Thanks Ben H. for suggesting the dma_sync API!)
      This patch also renames the "last_page_user" field of be_rx_page_info{}
      struct to "last_frag" to improve readability of the fixed code.

      Simon Wunderlich says:
      this series contains a header file proposal for MPLS labels. These
      labels do not seem to be properly defined in the kernel so far. We are
      developing a wired/wireless 802.21/MPLS switch and need to check the
      MPLS labels to use the traffic control info for transmissions over
      802.11 networks.
      Changes to third version:
       * rename mpls_label_stack to mpls_label (thanks Neil)
       * fix over-indendented closing brac (thanks Sergei)
       * add Johannes' Ack

      Simon Wunderlich authored
      MPLS labels may contain traffic control information, which should be
      evaluated and used by the wireless subsystem if present.
      Also check for IEEE 802.21 which is always network control traffic.

       7) Add missing locking in xfrm_migrade_state_find(), we must hold the
          per-namespace xfrm_state_lock while traversing the lists.  Fix from
          Steffen Klassert.
       8) Missing locking in ath9k driver, access to tid->sched must be done

       9) Fix two bugs in TCP fastopen.  First respect the size argument given

      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.

      mm: page_alloc: exempt GFP_THISNODE allocations from zone fairness · 27329369
      Johannes Weiner authored
      Jan Stancek reports manual page migration encountering allocation
      failures after some pages when there is still plenty of memory free, and
      bisected the problem down to commit 81c0a2bb
       ("mm: page_alloc: fair
      zone allocator policy").
      The problem is that GFP_THISNODE obeys the zone fairness allocation
      batches on one hand, but doesn't reset them and wake kswapd on the other
      hand.  After a few of those allocations, the batches are exhausted and
      the allocations fail.
      Fixing this means either having GFP_THISNODE wake up kswapd, or
      GFP_THISNODE not participating in zone fairness at all.  The latter
      seems safer as an acute bugfix, we can clean up later.

      mm: numa: bugfix for LAST_CPUPID_NOT_IN_PAGE_FLAGS · 1ae71d03
      Liu Ping Fan authored
      When doing some numa tests on powerpc, I triggered an oops bug.  I find
      it is caused by using page->_last_cpupid.  It should be initialized as
      "-1 & LAST_CPUPID_MASK", but not "-1".  Otherwise, in task_numa_fault(),
      we will miss the checking (last_cpupid == (-1 & LAST_CPUPID_MASK)).  And
      finally cause an oops bug in task_numa_group(), since the online cpu is
      less than possible cpu.  This happen with CONFIG_SPARSE_VMEMMAP disabled
