      bnx2x: use the default NAPI weight · 6fac4115
      Eric Dumazet authored
      BQL (Byte Queue Limits) proper operation needs TX completion
      being serviced in a timely fashion.
      
      bnx2x uses a non standard NAPI poll weight, and thats not fair to other
      napi poll handlers, and even not reasonable.
      
      Use the default value instead.

      net: introduce NAPI_POLL_WEIGHT · 82dc3c63
      Eric Dumazet authored
      Some drivers use a too big NAPI poll weight.
      
      This patch adds a NAPI_POLL_WEIGHT default value
      and issues an error message if a driver attempts
      to use a bigger weight.

        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

      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).

      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.

      rds: limit the size allocated by rds_message_alloc() · ece6b0a2

      kmalloc can satisfy."

      Pull fbdev UAPI disintegration from David Howells:
       "You'll be glad to here that the end is nigh for the UAPI patches.
        Only the fbdev/framebuffer piece remains now that the SCSI stuff has
        gone in.
      
        Here are the UAPI disintegration bits for the fbdev drivers.  It
        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."
      
      Yay.  No more uapi movement.  And hopefully no more big header file
      cleanups coming up either, it just tends to be very painful.
