732973c87f ARM: ux500: Correctly reference IRQs supplied by the AB8500 from Device Tree
The AB8500 driver has now been provided with IRQ domain support. This
means we can request IRQs from any of it's uses via Device Tree. This
patch advertises the AB8500 as an Interrupt Controller and provides the
correct calls in the format the driver expects.

Now that u5500 is obsolete, u8500 is the only user of the Nomadik
i2c driver. As such there is no requirement to differentiate between
initialisation values. By the time a new SoC is released, almost all
of the ux500 platform will be DT:ed, so we can make decisions based
on the compatible property instead.

2b667a2d80 ARM: ux500: Over-ride the DT device naming scheme for pinctrl
When pin control mapping tables are written the registered device
name is supplied for use in name-based searches within the pinctrl
driver. In the case of the DB8500 the string "pinctrl-db8500" is
used. However, when we register the driver with Device Tree, its
naming convention uses something that looks more like "pinctrl.2".

To work around the device naming inconsistencies between devices
registered via platform code and the ones registered by Device
Tree, we use AUXDATA to over-ride the Device Tree naming scheme.

0b17ba7258 powerpc: check_and_cede_processor() never cedes
Commit f948501b36 ("Make hard_irq_disable() actually hard-disable
interrupts") caused check_and_cede_processor to stop working.
->irq_happened will never be zero right after a hard_irq_disable
so the compiler removes the call to cede_processor completely.

The bug was introduced back in the lazy interrupt handling rework
of 3.4 but was hidden until recently because hard_irq_disable did
nothing.

This issue will eventually appear in 3.4 stable since the
hard_irq_disable fix is marked stable, so mark this one for stable
too.

2d773aa481 powerpc/ftrace: Do not trace restore_interrupts()
As I was adding code that affects all archs, I started testing function
tracer against PPC64 and found that it currently locks up with 3.4
kernel. I figured it was due to tracing a function that shouldn't be, so
I went through the following process to bisect to find the culprit:

 cat /debug/tracing/available_filter_functions > t
 num=`wc -l t`
 sed -ne "1,${num}p" t > t1
 let num=num+1
 sed -ne "${num},$p" t > t2
 cat t1 > /debug/tracing/set_ftrace_filter
 echo function /debug/tracing/current_tracer
 <failed? bisect t1, if not bisect t2>

It finally came down to this function: restore_interrupts()

I'm not sure why this locks up the system. It just seems to prevent
scheduling from occurring. Interrupts seem to still work, as I can ping
the box. But all user processes freeze.

When restore_interrupts() is not traced, function tracing works fine.

c58ce2b1e3 ppc64: fix missing to check all bits of _TIF_USER_WORK_MASK in preempt
In entry_64.S version of ret_from_except_lite, you'll notice that
in the !preempt case, after we've checked MSR_PR we test for any
TIF flag in _TIF_USER_WORK_MASK to decide whether to go to do_work
or not. However, in the preempt case, we do a convoluted trick to
test SIGPENDING only if PR was set and always test NEED_RESCHED ...
but we forget to test any other bit of _TIF_USER_WORK_MASK !!! So
that means that with preempt, we completely fail to test for things
like single step, syscall tracing, etc...

This should be fixed as the following path:

 - Test PR. If not set, go to resume_kernel, else continue.

 - If go resume_kernel, to do that original do_work.

 - If else, then always test for _TIF_USER_WORK_MASK to decide to do
that original user_work, else restore directly.

The problem is that currently none of the clocks are being registered for
OMAP4470 devices and so on boot-up no clocks can be found and the kernel panics.

This fix allows the kernel to boot without failure using a simple RAMDISK file
system on OMAP4470 blaze board.

Per feedback from Paul and Benoit the 4470 clock data is incomplete for new
modules such as the 2D graphics block that has been added to the 4470.
Therefore add a warning to indicate that the clock data is incomplete.

removing the static in the header file, it created a duplicate definition
in the .c and the .h files, resuling in a build error:

Fix this by removing the duplicate dummy entry from the C file.

4ad3341130 x86, cpufeature: Rename X86_FEATURE_DTS to X86_FEATURE_DTHERM
It makes sense to label "Digital Thermal Sensor" as "DTS", but
unfortunately the string "dts" was already used for "Debug Store", and
/proc/cpuinfo is a user space ABI.

Therefore, rename this to "dtherm".

This conflict went into mainline via the hwmon tree without any x86
maintainer ack, and without any kind of hint in the subject.

593f473554 ARM: dma-mapping: fix buffer chunk allocation order
IOMMU-aware dma_alloc_attrs() implementation allocates buffers in
power-of-two chunks to improve performance and take advantage of large
page mappings provided by some IOMMU hardware. However current code, due
to a subtle bug, allocated those chunks in the smallest-to-largest
order, what completely killed all the advantages of using larger than
page chunks. If a 4KiB chunk has been mapped as a first chunk, the
consecutive chunks are not aligned correctly to the power-of-two which
match their size and IOMMU drivers were not able to use internal
mappings of size other than the 4KiB (largest common denominator of
alignment and chunk size).

This patch fixes this issue by changing to the correct largest-to-smallest
chunk size allocation sequence.

0fa1f0609a ARM: Orion: Fix Virtual/Physical mixup with watchdog
The orion watchdog is expecting to be passed the physcial address of
the hardware, and will ioremap() it to give a virtual address it will
use as the base address for the hardware. However, when creating the
platform resource record, a virtual address was being used.

Add the necassary #define's so we can pass the physical address as
expected.

Tested on Kirkwood and Orion5x.
