Conflicts:
	drivers/net/ethernet/emulex/benet/be.h
	drivers/net/netconsole.c
	net/bridge/br_private.h

Three mostly trivial conflicts.

The net/bridge/br_private.h conflict was a function signature (argument
addition) change overlapping with the extern removals from Joe Perches.

In drivers/net/netconsole.c we had one change adjusting a printk message
whilst another changed "printk(KERN_INFO" into "pr_info(".

Lastly, the emulex change was a new inline function addition overlapping
with Joe Perches's extern removals.

 "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"

29114fd7db ARM: integrator: deactivate timer0 on the Integrator/CP
This fixes a long-standing Integrator/CP regression from
commit 870e2928cf
"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secondary timer as they have been superceded by the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

3c1532df5c ARM: 7851/1: check for number of arguments in syscall_get/set_arguments()
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().

016c12d2fb ARM: OMAP3: Fix hardware detection for omap3630 when booted with device tree
SoC family definitions at the moment are reactive to board needs
as a result, beagle-xm would matchup with ti,omap3 which invokes
omap3430_init_early instead of omap3630_init_early. Obviously, this is
the wrong behavior.

With clock node dts conversion, we get the following warnings before
system hangs as a result and 3630 based platforms fails to boot
(uart4 clocks are only present in OMAP3630 and not present in
OMAP3430):

...

1dc1c33879 ARM: OMAP2: gpmc-onenand: fix sync mode setup with DT
With DT-based boot, the GPMC OneNAND sync mode setup does not work
correctly. During the async mode setup, sync flags gets incorrectly
set in the onenand_async data and the system crashes during the async
setup. Also, the sync mode never gets set in gpmc_onenand_data->flags, so
even without the crash, the actual sync mode setup would never be called.

The patch fixes this by adjusting the gpmc_onenand_data->flags when the
data is read from the DT. Also while doing this we force the onenand_async
to be always async.

The patch enables to use the following DTS chunk (that should correspond
the arch/arm/mach-omap2/board-rm680.c board file setup) with Nokia N950,
which currently crashes with 3.12-rc1. The crash output can be also
found below.

bc41b8724f ARM: 7846/1: Update SMP_ON_UP code to detect A9MPCore with 1 CPU devices
The generic code is well equipped to differentiate between
SMP and UP configurations.However, there are some devices which
use Cortex-A9 MP core IP with 1 CPU as configuration. To let
these SOCs to co-exist in a CONFIG_SMP=y build by leveraging
the SMP_ON_UP support, we need to additionally check the
number the cores in Cortex-A9 MPCore configuration. Without
such a check in place, the startup code tries to execute
ALT_SMP() set of instructions which lead to CPU faults.

The issue was spotted on TI's Aegis device and this patch
makes now the device work with omap2plus_defconfig which
enables SMP by default. The change is kept limited to only
Cortex-A9 MPCore detection code.

Note that if any future SoC *does* use 0x0 as the PERIPH_BASE, then
the SCU address check code needs to be #ifdef'd for for the Aegis
platform.

This fixes a regression for kernels after v3.2

After commit 72662e0108
ARM: head.S: only include __turn_mmu_on in the initial identity mapping

Zaurus PXA devices call sharpsl_save_param() during fixup and hang on
boot because memcpy refers to physical addresses no longer valid if the
MMU is setup.
Zaurus collie (SA1100) is unaffected (function is called in init_machine).

The code was making assumptions and for PXA the virtual address
should have been used before.

262576fffe ARM: 7843/1: drop asm/types.h from generic-y
Commit 09096f6 (ARM: 7822/1: add workaround for ambiguous C99 stdint.h
types) introduced an ARM specific 'asm/types.h' to work around some
ambiguities in the definitions of 32 bit types. Hence, we will not be
needing the generic version anymore.
