Pull ARM SoC fixes from Olof Johansson:
 "There's really only one bugfix in this branch, which is a fix for
  timers on the integrator platform.  Since Linus Walleij is
  resurrecting support for the platform it seems valuable to get the fix
  into 3.12 even though the regression has been around a while.

  The rest are a handful of maintainers updates.  If you prefer to hold
  those until 3.13 then just merge the first patch on the branch which
  is the fix"

 "Sorry I let so much accumulate, I was in Buffalo and wanted a few
  things to cook in my tree for a while before sending to you.  Anyways,
  it's a lot of little things as usual at this stage in the game"

 1) Make bonding MAINTAINERS entry reflect reality, from Andy
    Gospodarek.

 2) Fix accidental sock_put() on timewait mini sockets, from Eric
    Dumazet.

    addresses, from François CACHEREUL.

    from Felix Fietkau.

    Kleine-Budde.

11) Fix permission checks in sysctls to use current_euid() instead of
    current_uid().  From Eric W Biederman.

12) IPSEC policies can go away while a timer is still pending for them,
    add appropriate ref-counting to fix, from Steffen Klassert.

13) Fix mis-programming of FDR and RMCR registers on R8A7740 sh_eth
    chips, from Nguyen Hong Ky and Simon Horman.

15) IPV6 GRE tunnel MTU upper limit is miscalculated, from Oussama
    Ghorbel.

16) Fix typo in fq_change(), we were assigning "initial quantum" to
    "quantum".  From Eric Dumazet.

17) Set a more appropriate sk_pacing_rate for non-TCP sockets, otherwise
    FQ packet scheduler does not pace those flows properly.  Also from
    Eric Dumazet.

18) rtlwifi miscalculates packet pointers, from Mark Cave-Ayland.

19) l2tp_xmit_skb() can be called from process context, not just softirq
    context, so we must always make sure to BH disable around it.  From
    Eric Dumazet.

20) On qdisc reset, we forget to purge the RB tree of SKBs in netem
    packet scheduler.  From Stephen Hemminger.

    applied.  From Fan Du and Vlad Yasevich.

24) Tail loss probing in TCP leaves the socket in the wrong congestion
    avoidance state.  From Yuchung Cheng.

26) Integer underflow and dual-assignment in YAM hamradio driver, from
    Dan Carpenter.

27) If we are going to mangle a packet in tcp_set_skb_tso_segs() we must
    unclone it.  This fixes various hard to track down crashes in
    drivers where the SKBs ->gso_segs was changing right from underneath
    the driver during TX queueing.  From Eric Dumazet.

28) Fix the handling of VLAN IDs, and in particular the special IDs 0
    and 4095, in the bridging layer.  From Toshiaki Makita.

29) Another info leak, this time in wanxl WAN driver, from Salva Peiró.

30) Fix race in socket credential passing, from Daniel Borkmann.

31) WHen NETLABEL is disabled, we don't validate CIPSO packets properly,

    Fragmentation Offload output paths, from Jiri Pirko.

33) Virtual Function fixes in bnx2x driver from Yuval Mintz and Ariel
    Elior.

34) When we removed the explicit neighbour pointer from ipv6 routes a
    slight regression was introduced for users such as IPVS, xt_TEE, and
    raw sockets.  We mix up the users requested destination address with
    the routes assigned nexthop/gateway.  From Julian Anastasov and
    Simon Horman.

35) Fix stack overruns in rt6_probe(), the issue is that can end up
    doing two full packet xmit paths at the same time when emitting
    neighbour discovery messages.  From Hannes Frederic Sowa.

36) davinci_emac driver doesn't handle IFF_ALLMULTI correctly, from
    Mariusz Ceier.

37) Make sure to set TCP sk_pacing_rate after the first legitimate RTT
    sample, from Neal Cardwell.

38) Wrong netlink attribute passed to xfrm_replay_verify_len(), from
    Steffen Klassert.

Pull device tree fixes and reverts from Grant Likely:
 "One bug fix and three reverts.  The reverts back out the slightly
  controversial feeding the entire device tree into the random pool and
  the reserved-memory binding which isn't fully baked yet.  Expect the
  reserved-memory patches at least to resurface for v3.13.

  The bug fixes removes a scary but harmless warning on SPARC that was
  introduced in the v3.12 merge window.  v3.13 will contain a proper fix
  that makes the new code work on SPARC.

  On the plus side, the diffstat looks *awesome*.  I love removing lines
  of code"

no consensus on the bindings for the reserved memory, so the code for
handing it will be reverted.

Pull ARM fixes from Russell King:

This fixes a long-standing Integrator/CP regression from
commit 870e2928cf3368ca9b06bc925d0027b0a56bcd8e
"ARM: integrator-cp: convert use CLKSRC_OF for timer init"

When this code was introduced, the both aliases pointing the
system to use timer1 as primary (clocksource) and timer2
as secondary (clockevent) was ignored, and the system would
simply use the first two timers found as clocksource and
clockevent.

However this made the system timeline accelerate by a
factor x25, as it turns out that the way the clocking
actually works (totally undocumented and found after some
trial-and-error) is that timer0 runs @ 25MHz and timer1
and timer2 runs @ 1MHz. Presumably this divider setting
is a boot-on default and configurable albeit the way to
configure it is not documented.

So as a quick fix to the problem, let's mark timer0 as
disabled, so the code will chose timer1 and timer2 as it
used to.

This also deletes the two aliases for the primary and
secondary timer as they have been superceded by the
auto-selection

In ftrace_syscall_enter(),
    syscall_get_arguments(..., 0, n, ...)
        if (i == 0) { <handle ORIG_r0> ...; n--;}
        memcpy(..., n * sizeof(args[0]));
If 'number of arguments(n)' is zero and 'argument index(i)' is also zero in
syscall_get_arguments(), none of arguments should be copied by memcpy().
Otherwise 'n--' can be a big positive number and unexpected amount of data
will be copied. Tracing system calls which take no argument, say sync(void),
may hit this case and eventually make the system corrupted.
This patch fixes the issue both in syscall_get_arguments() and
syscall_set_arguments().

THis is because the Exynos u-boot, for example on the Chromebooks, doesn't set
up the CNTFRQ register as expected by arch_timer. Instead, we have to specify
the frequency in the device tree like this.
