Pull x86/intel-mid changes from Ingo Molnar:
"Update the 'intel mid' (mobile internet device) platform code as Intel
is rolling out more SoC designs.
This gets rid of most of the 'MRST' platform code in the process,
mostly by renaming and shuffling code around into their respective
'intel-mid' platform drivers"

x86, intel-mid: Do not re-introduce usage of obsolete __cpuinit
intel_mid: Move platform device setups to their own platform_<device>.* files
x86: intel-mid: Add section for sfi device table

mrst is used as common name to represent all intel_mid type
soc's. But moorsetwon is just one of the intel_mid soc. So
renamed them to use intel_mid.
This patch mainly renames the variables and related
functions that uses *mrst* prefix with *intel_mid*.
To ensure that there are no functional changes, I have compared
the objdump of related files before and after rename and found
the only difference is symbol and name changes.

It's incredibly difficult to diagnose early EFI boot issues without
special hardware because earlyprintk=vga doesn't work on EFI systems.
Add support for writing to the EFI framebuffer, via earlyprintk=efi,
which will actually give users a chance of providing debug output.

Shared faults can lead to lots of unnecessary page migrations,
slowing down the system, and causing private faults to hit the
per-pgdat migration ratelimit.
This patch adds sysctl numa_balancing_migrate_deferred, which specifies
how many shared page migrations to skip unconditionally, after each page
migration that is skipped because it is a shared fault.
This reduces the number of page migrations back and forth in
shared fault situations. It also gives a strong preference to
the tasks that are already running where most of the memory is,
and to moving the other tasks to near the memory.
Testing this with a much higher scan rate than the default
still seems to result in fewer page migrations than before.
Memory seems to be somewhat better consolidated than previously,
with multi-instance specjbb runs on a 4 node system.

This patch favours moving tasks towards NUMA node that recorded a higher
number of NUMA faults during active load balancing. Ideally this is
self-reinforcing as the longer the task runs on that node, the more faults
it should incur causing task_numa_placement to keep the task running on that
node. In reality a big weakness is that the nodes CPUs can be overloaded
and it would be more efficient to queue tasks on an idle node and migrate
to the new node. This would require additional smarts in the balancer so
for now the balancer will simply prefer to place the task on the preferred
node for a PTE scans which is controlled by the numa_balancing_settle_count
sysctl. Once the settle_count number of scans has complete the schedule
is free to place the task on an alternative node if the load is imbalanced.

being scanned
The NUMA PTE scan rate is controlled with a combination of the
numa_balancing_scan_period_min, numa_balancing_scan_period_max and
numa_balancing_scan_size. This scan rate is independent of the size
of the task and as an aside it is further complicated by the fact that
numa_balancing_scan_size controls how many pages are marked pte_numa and
not how much virtual memory is scanned.
In combination, it is almost impossible to meaningfully tune the min and
max scan periods and reasoning about performance is complex when the time
to complete a full scan is is partially a function of the tasks memory
size. This patch alters the semantic of the min and max tunables to be
about tuning the length time it takes to complete a scan of a tasks occupied
virtual address space. Conceptually this is a lot easier to understand. There
is a "sanity" check to ensure the scan rate is never extremely fast based on
the amount of virtual memory that should be scanned in a second. The default
of 2.5G seems arbitrary but it is to have the maximum scan rate after the
patch roughly match the maximum scan rate before the patch was applied.
On a similar note, numa_scan_period is in milliseconds and not
jiffies. Properly placed pages slow the scanning rate but adding 10 jiffies
to numa_scan_period means that the rate scanning slows depends on HZ which
is confusing. Get rid of the jiffies_to_msec conversion and treat it as ms.

Pull RCU updates from Ingo Molnar:
"The main RCU changes in this cycle are:
- Idle entry/exit changes, to throttle callback execution and other
refinements to speed up kbuild, primarily to address performance
issues located by Tibor Billes.
- Grace-period related changes, primarily to aid in debugging,
inspired by an -rt debugging session.
- Code reorganization moving RCU's source files into its own
kernel/rcu/ directory.
- RCU documentation updates
- Miscellaneous fixes.
Note, the following commit:
5c889690aa08 mm: Place preemption point in do_mlockall() loop
is identical to the commit already in your tree via email:

Pull ARM SoC DT updates from Olof Johansson:
"Most of this branch consists of updates, additions and general churn
of the device tree source files in the kernel (arch/arm/boot/dts).
Besides that, there are a few things to point out:
- Lots of platform conversion on OMAP2+, with removal of old board
files for various platforms.
- Final conversion of a bunch of ux500 (ST-Ericsson) platforms as
well
- Some updates to pinctrl and other subsystems. Most of these are
for DT-enablement of the various platforms and acks have been
collected"

On OMAP we have co-processor IPs, memory controllers,
GPIOs which control regulators and power switches to
PMIC, and SoC internal Bus IPs, some or most of which
should either not be reset or idled or both at init.
(In some cases there are erratas which prevent an IP
from being reset)
Have a way to pass this information from DT.
Update the am33xx/omap4 and omap5 dtsi files with the
new bindings for modules which either should not be
idled. reset or both. A later patch would cleanup the
same information that exists today as part of the hwmod
data files.

Remove the list of possible pin configurations from the documentation
file and create header files containing those definitions.
This eliminates the need for error-prone manual lookup of those values
in the documentation and guarantees consistency between the human
readable representation of the pad function in the .dts file and the
actual binary value used in DT.

We need the fixes in v3.12-rc5, dts changes in omap-for-v3.13/dt, and
the platform data quirk changes in omap-for-v3.13/quirk to start

From Tony Lindgren:
Changes needed to prepare for making omap3 device tree only:
- Always build in board-generic, and add pdata quirks and auxdata
support for it so we have all the pdata related quirks
in the same place.
- Merge of the drivers/pinctrl changes that are needed for PM
to continue working on omap3 and also needed for other omaps
eventually. The three pinctrl related patches have been acked
by Linus Walleij and are pulled into both the pinctrl tree
and this branch.
- Few defconfig related changes for drivers needed.

The pin control registers can have interrupts for example
for device wake-up. These interrupts can be treated as a
chained interrupt controller as suggested earlier by
Linus Walleij <linus.walleij@linaro.org>.
This patch adds support for interrupts in a way that
should be pretty generic, and works for the omaps that
support wake-up interrupts. On omaps, there's an
interrupt enable and interrupt status bit for each pin.
The two pinctrl domains on omaps share a single interrupt
from the PRM chained interrupt handler. Support for
other similar hardware should be easy to add.
Note that this patch does not attempt to handle the
wake-up interrupts automatically unlike the earlier
patches. This patch allows the device drivers to do
a request_irq() on the wake-up pins as needed. I'll
try to do also a separate generic patch for handling
the wake-up events automatically.
Also note that as this patch makes the pinctrl-single
an irq controller, the current bindings need some
extra trickery to use interrupts from two different
interrupt controllers for the same driver. So it
might be worth waiting a little on the patches
enabling the wake-up interrupts from drivers as there
should be a generic way to handle it coming. And also
there's been discussion of interrupts-extended binding
for using interrupts from multiple interrupt controllers.
In any case, this patch should be ready to go allowing
handling the wake-up interrupts in a generic way, or
separately from the device drivers.

The "mentor,musb" binding isn't documented so I was about
to document it.
The node is missing a few properties for configuration like
"multipoint", "dyn_fifo", "num_eps" or "ram_bits". However
I am not sure "missing" is the right word here because some
of those informations might be obtained from the chip itself
but it is not done (yet).
Further the ePARP 2.3.1 says the matching goes from left to
right taking the fist match. Right now there is jus a driver
for "stericsson,db8500-musb" and none for "mentor,musb".
I'm not 100% that it is simply possible to have a generic
since even for DMA we have ifdefs in the driver between
"generic mentor dma" and "ux500 dma" and I mean within musb
and not the dma code.
For that reason (that I am not sure a generic musb binding
is possible and how its binding / required properties will
look like) and the reason that we have here a minor binding
without a driver to look at I suggest to remove that binding.
If the majority of people prefer to keep this binding I'm
curious how the documentation of the binding should look like.

This patch extends vic_of_init to parse valid interrupt sources
and resume sources masks from device tree.
If mask values are not specified in device tree, all sources
are assumed to be valid, as before this patch.

Pull ARM driver updates from Olof Johansson:
"Updates of SoC-near drivers and other driver updates that makes more
sense to take through our tree. In this case it's involved:
- Some Davinci driver updates that has required corresponding
platform code changes (gpio mostly)
- CCI bindings and a few driver updates
- Marvell mvebu patches for PCI MSI support (could have gone through
the PCI tree for this release, but they were acked by Bjorn for
3.12 so we kept them through arm-soc).
- Marvell dove switch-over to DT-based PCIe configuration
- Misc updates for Samsung platform dmaengine drivers"

git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/drivers
From Kukjin Kim, this branch adds device-tree support to the DMA controller
on the older Samsung SoCs. It also adds support for one of the missing SoCs
in the family (2410).
The driver has been Ack:ed by Vinod Koul, but is merged through here due
to dependencies with platform code.
