       "A moderately sized pile of fixes, some specifically for merge window
        introduced regressions although others are for longer standing items
        and have been queued up for -stable.
      
        I'm kind of tired of all the RDS protocol bugs over the years, to be
        honest, it's way out of proportion to the number of people who
        actually use it.

            Kadlecsik.

        12) Omit trailing FCS from frames received in BGMAC driver, from Hauke

        13) Missing socket refcount release in L2TP, from Guillaume Nault.
      
        14) sctp_endpoint_init should respect passed in gfp_t, rather than use
            GFP_KERNEL unconditionally.  From Dan Carpenter.
      
        15) Add AISX AX88179 USB driver, from Freddy Xin.
      
        16) Remove MAINTAINERS entries for drivers deleted during the merge
            window, from Cesar Eduardo Barros.

            that the user's request length makes sense, from Cong Wang.

            bogus, definition.  From Cong Wang.
      
        19) Fix deadlocks in FEC driver by moving TX reclaim into NAPI poll,
            from Frank Li.  Also, fix a build error introduced in the merge
            window.

      hw_random: make buffer usable in scatterlist. · f7f154f1
      Rusty Russell authored
      virtio_rng feeds the randomness buffer handed by the core directly
      into the scatterlist, since commit bb347d98.
      
      However, if CONFIG_HW_RANDOM=m, the static buffer isn't a linear address
      (at least on most archs).  We could fix this in virtio_rng, but it's actually
      far easier to just do it in the core as virtio_rng would have to allocate
      a buffer every time (it doesn't know how much the core will want to read).

      We should not update ts_recent and call tcp_rcv_rtt_measure_ts() both
      before and after going to step5. That wastes CPU and double-counts the
      receiver-side RTT sample.

      net: ipv6: Don't purge default router if accept_ra=2 · 3e8b0ac3
      Lorenzo Colitti authored
      Setting net.ipv6.conf.<interface>.accept_ra=2 causes the kernel
      to accept RAs even when forwarding is enabled. However, enabling
      forwarding purges all default routes on the system, breaking
      connectivity until the next RA is received. Fix this by not
      purging default routes on interfaces that have accept_ra=2.

        Only the fbdev/framebuffer piece remains now that the SCSI stuff has

        appears that Florian hasn't had time to deal with my patch, but back
        in December he did say he didn't mind if I pushed it forward."

      Pull second set of slave-dmaengine updates from Vinod Koul:
       "Arnd's patch moves the dw_dmac to use generic DMA binding.  I agreed
        to merge this late as it will avoid the conflicts between trees.
      
        The second patch from Matt adding a dma_request_slave_channel_compat
        API was supposed to be picked up, but somehow never got picked up.
        Some patches dependent on this are already in -next :("
      
      * 'next' of git://git.infradead.org/users/vkoul/slave-dma:
        dmaengine: dw_dmac: move to generic DMA binding
        dmaengine: add dma_request_slave_channel_compat()
