      Pull ecryptfs fixes from Tyler Hicks:
       "Minor code cleanups and new Kconfig option to disable /dev/ecryptfs
      
        The code cleanups fix up W=1 compiler warnings and some unnecessary
        checks.  The new Kconfig option, defaulting to N, allows the rarely
        used eCryptfs kernel to userspace communication channel to be compiled
        out.  This may be the first step in it being eventually removed."
      
      Hmm.  I'm not sure whether these should be called "fixes", and it
      probably should have gone in the merge window.  But I'll let it slide.

        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.

        19) Fix deadlocks in FEC driver by moving TX reclaim into NAPI poll,

      in the FSCR (Facility Status & Control Register) incase some firmwares don't

      powerpc: Avoid link stack corruption in MMU on syscall entry path · 6a404806
      Michael Neuling authored
      Currently we use the link register to branch up high in the early MMU on
      syscall entry path.  Unfortunately, this trashes the link stack as the
      address we are going to is not associated with the earlier mflr.
      
      This patch simply converts us to used the count register (volatile over
      syscalls anyway) instead.  This is much better at predicting in this
      scenario and doesn't trash link stack causing a bunch of additional
      branch mispredicts later.  Benchmarking this on POWER8 saves a bunch of
      cycles on Anton's null syscall benchmark here:

      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).

      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.

      net: fec: put tx to napi poll function to fix dead lock · de5fb0a0

      up stack ndo_start_xmit already hold lock.
      fec_enet_start_xmit needn't spin lock.
      stat_xmit just update fep->cur_tx
      fec_enet_tx just update fep->dirty_tx
      
      Reserve a empty bdb to check full or empty
      cur_tx == dirty_tx    means full
      cur_tx == dirty_tx +1 means empty
      
      So needn't is_full variable.

      eCryptfs: allow userspace messaging to be disabled · 290502be
      Kees Cook authored
      
      
      When the userspace messaging (for the less common case of userspace key
      wrap/unwrap via ecryptfsd) is not needed, allow eCryptfs to build with
      it removed. This saves on kernel code size and reduces potential attack
      surface by removing the /dev/ecryptfs node.
