      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.

       "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.
      
         1) Fix missing range initialization in netfilter IPSET, from Jozsef
            Kadlecsik.
      
         2) ieee80211_local->tim_lock needs to use BH disabling, from Johannes

            fix from Dmitry Kravkov.
      
         7) Missing cfgspace_lock initialization in BCMA driver.

        11) Fix phy_device memory leak, from Petr Malat.
      
        12) Omit trailing FCS from frames received in BGMAC driver, from Hauke
            Mehrtens.
      
        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.
      
        17) RDS protocol can try to allocate huge amounts of memory, check
            that the user's request length makes sense, from Cong Wang.
      
        18) SCTP should use the provided KMALLOC_MAX_SIZE instead of it's own,
            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.
      
        20) Fix bogus purging of default routes in ipv6, from Lorenzo Colitti.

      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.

      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

       "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.
