OMAP_MODE_GPIO() macro verified only OMAP_MUX_MODE4.
It is not correct for following platforms:
2430 - gpio mux mode 3
44xx - gpio mux mode 3
54xx - gpio mux mode 6
Patch reserves first 3 bits in partition flags for storing gpio mux
mode in same format as stored in control pad register.
Modified OMAP_MODE_GPIO() macro to handle all possible cases of gpio mux mode.
Modified omap_mux_init() flags of omap34xx to include OMAP_MUX_GPIO_IN_MODE4.

The i2c handling in tfp410 driver, which handles converting parallel RGB
to DVI, was changed in 958f2717b8
(OMAPDSS: TFP410: pdata rewrite). The patch changed what value the
driver considers as invalid/undefined. Before the patch, 0 was the
invalid value, but as 0 is a valid bus number, the patch changed this to
-1.
However, the fact was missed that many board files do not define the bus
number at all, thus it's left to 0. This causes the driver to fail to
get the i2c bus, exiting from the driver's probe with an error, meaning
that the DVI output does not work for those boards.
This patch fixes the issue by changing the i2c_bus number field in the
driver's platform data from u16 to int, and setting the bus number to -1
in the board files for the boards that did not define the bus. The
exception is devkit8000, for which the bus is set to 1, which is the
correct bus for that board.
The bug exists in v3.5+ kernels.

arch/arm/mach-omap2/timer.c:395:19: warning: ‘omap2_sync32k_clocksource_init’
defined but not used [-Wunused-function]
This issue was introduced by commit 6f80b3b (ARM: OMAP2+: timer: remove
CONFIG_OMAP_32K_TIMER) where the omap2_sync32k_clocksource_init() is no
longer referenced by the timer initialisation function for the AM335x
device as it has no 32k-sync timer.
Fix this by adding the "__maybe_unused" compiler directive to the
omap2_sync32k_clocksource_init() function to indicate that this function
may be used for certain configurations.

In commit fa6d79d (ARM: OMAP: Add initialisation for the real-time
counter), the function realtime_counter_init() was added. However, if
the kernel configuration option CONFIG_SOC_OMAP5 is not selected then
the following compiler warning is observed.
CC arch/arm/mach-omap2/timer.o
arch/arm/mach-omap2/timer.c:489:20: warning: ‘realtime_counter_init’
defined but not used [-Wunused-function]
Commit fa6d79d also introduced the kernel configuration option
CONFIG_SOC_HAS_REALTIME_COUNTER. If this option is not selected then the
a stub function for realtime_counter_init() is defined.
For non-OMAP5 devices, there is no realtime counter and so
realtime_counter_init() function and stub function are not used for
these devices. Therefore, fix this warning by only allowing the kernel
configuration option CONFIG_SOC_HAS_REALTIME_COUNTER to be enabled for
OMAP5 devices.

This branch contains a largeish set of updates of power management and
clock setup. The bulk of it is for OMAP/AM33xx platforms, but also a
few around hotplug/suspend/resume on Exynos.
It includes a split-up of some of the OMAP clock data into separate
files which adds to the diffstat, but gross delta is fairly reasonable.

Pull big execve/kernel_thread/fork unification series from Al Viro:
"All architectures are converted to new model. Quite a bit of that
stuff is actually shared with architecture trees; in such cases it's
literally shared branch pulled by both, not a cherry-pick.
A lot of ugliness and black magic is gone (-3KLoC total in this one):
- kernel_thread()/kernel_execve()/sys_execve() redesign.
We don't do syscalls from kernel anymore for either kernel_thread()
or kernel_execve():
kernel_thread() is essentially clone(2) with callback run before we
return to userland, the callbacks either never return or do
successful do_execve() before returning.
kernel_execve() is a wrapper for do_execve() - it doesn't need to
do transition to user mode anymore.
As a result kernel_thread() and kernel_execve() are
arch-independent now - they live in kernel/fork.c and fs/exec.c
resp. sys_execve() is also in fs/exec.c and it's completely
architecture-independent.
- daemonize() is gone, along with its parts in fs/*.c
- struct pt_regs * is no longer passed to do_fork/copy_process/
copy_thread/do_execve/search_binary_handler/->load_binary/do_coredump.
- sys_fork()/sys_vfork()/sys_clone() unified; some architectures
still need wrappers (ones with callee-saved registers not saved in
pt_regs on syscall entry), but the main part of those suckers is in
kernel/fork.c now."

A few shmobile platforms that are stale have been removed, some
defconfig updates for various boards selecting new features such as
pinctrl subsystem support, and various updates enabling peripherals,
etc."
Fix up conflicts mostly as per Olof.

This contains the bulk of new SoC development for this merge window.
Two new platforms have been added, the sunxi platforms (Allwinner A1x
SoCs) by Maxime Ripard, and a generic Broadcom platform for a new
series of ARMv7 platforms from them, where the hope is that we can
keep the platform code generic enough to have them all share one mach
directory. The new Broadcom platform is contributed by Christian Daudt.
Highbank has grown support for Calxeda's next generation of hardware,
ECX-2000.
clps711x has seen a lot of cleanup from Alexander Shiyan, and he's also
taken on maintainership of the platform.
Beyond this there has been a bunch of work from a number of people on
converting more platforms to IRQ domains, pinctrl conversion, cleanup
and general feature enablement across most of the active platforms.

Commit d065bd810b
(mm: retry page fault when blocking on disk transfer) and
commit 37b23e0525
(x86,mm: make pagefault killable)
The above commits introduced changes into the x86 pagefault handler
for making the page fault handler retryable as well as killable.
These changes reduce the mmap_sem hold time, which is crucial
during OOM killer invocation.
Port these changes to mn10300.

The debug polling interface for the SoC serial ports did not work in the case
where the serial ports were not also used as a console. In that case, the
uart driver startup function will not be called so tx and rx would not be
enabled in the hardware control register. Also, vdma interrupts would not be
enabled which the poll_get_char function relied on. This patch makes sure that
the rx and tx enables are set as a consequence of the uart set_termios call
which is the only initialization done for the debug polling interface. Also,
the poll_get_char now handles the case where vdma interrupts are not enabled.

The SoC serial port driver uses a high priority interrupt to handle tx of
characters in the tx ring buffer. The driver needs to disable/enable this IRQ
from outside of irq context. The original code to do this is not foolproof on
SMP machines because the IRQ running on one core could still access the serial
port for a short time after the driver running on another core disables the
interrupt. This patch adds a flag to tell the IRQ handler that the driver
wants to disable the interrupt. After seeing the flag, the IRQ handler will
immediately disable the interrupt and exit. After setting the flag, the driver
will wait for interrupt to be disabled by the IRQ handler.

The builtin SoC serial ports have no FIFOs and use a virtual DMA mechanism
based on high priority IRQs to avoid overruns. These high priority interrupts
are pinned to cpu#0 on SMP systems. This patch fixes a problem with SMP where
the set_intr_level() interface is used to set the priority for these IRQs. The
set_intr_level() function sets priority on the local cpu but on SMP systems,
this code may be run on some other cpu than the one handling the interrupts.
Instead of setting interrupt level explicitly, this patch uses a special
irq_chip for these interrupts so that the mask/unmask methods can set the
interrupt level implicitly.

The irq_set_affinity handler for the mn10300 cpu pic had some hard-coded IRQs
which were not to be migrated from one cpu to another. This patch cleans those
up by using a combination of IRQF_NOBALANCING and specialized irq chips with
no irq_set_affinity handler. This maintains the previous behavior by using
generic IRQ interfaces rather than hard coding IRQ numbers in the default
irq_set_affinity handler.

Pull ARM OMAP serial updates from Russell King:
"This series is a major reworking of the OMAP serial driver code fixing
various bugs in the hardware-assisted flow control, extending up into
serial_core for a couple of issues. These fixes have been done as a
set of progressive changes and transformations in the hope that no new
bugs will be introduced by this series.
The problems are many-fold, from the driver not being informed about
updated settings, to the driver not knowing what the intentions of the
upper layers are.
The first four patches tackle the serial_core layer, allowing it to
provide the necessary information to drivers, and the remaining
patches allow the OMAP serial driver to take advantage of this.
This brings hardware assisted RTS/CTS and XON/OFF flow control into a
useful state.
These patches have been in linux-next for most of the last cycle;
indeed they predate the previous merge window. They've also been
posted to the OMAP people."

Pull x86 BSP hotplug changes from Ingo Molnar:
"This tree enables CPU#0 (the boot processor) to be onlined/offlined on
x86, just like any other CPU. Enabled on Intel CPUs for now.
Allowing this required the identification and fixing of latent CPU#0
assumptions (such as CPU#0 initializations, etc.) in the x86
architecture code, plus the identification of barriers to
BSP-offlining, such as active PIC interrupts which can only be
serviced on the BSP.
It's behind a default-off option, and there's a debug option that
allows the automatic testing of this feature.
The motivation of this feature is to allow and prepare for true
CPU-hotplug hardware support: recent changes to MCE support enable us
to detect a deteriorating but not yet hard-failing L1/L2 cache on a
CPU that could be soft-unplugged - or a failing L3 cache on a
multi-socket system.
Note that true hardware hot-plug is not yet fully enabled by this,
because that requires a special platform wakeup sequence to be sent to
the freshly powered up CPU#0. Future patches for this are planned,
once such a platform exists. Chicken and egg"

"The biggest change affects group scheduling: we now track the runnable
average on a per-task entity basis, allowing a smoother, exponential

binary on-the-runqueue/off-the-runqueue load weight method.
This will inevitably disturb workloads that were in some sort of
borderline balancing state or unstable equilibrium, so an eye has to
be kept on regressions.
For that reason the new load average is only limited to group
scheduling (shares distribution) at the moment (which was also hurting
the most from the prior, crude weight calculation and whose scheduling
quality wins most from this change) - but we plan to extend this to
regular SMP balancing as well in the future, which will simplify and
speed up things a bit.
Other changes involve ongoing preparatory work to extend NOHZ to the
scheduler as well, eventually allowing completely irq-free user-space
execution."
