Properly register on-chip interrupt using the irqdomain logic. The
number of interrupts is taken from the devicetree node. That includes
the following changes:
- cpu_has_ipr() was converted from an inline function to a static bool
variable, so it can be set using the "marvell,intc-priority" property
inside the device node of the tree.
- IRQ_BASE was converted from a macro to a runtime variable so that it
can be initialized dynamically from the DT init code.
- irq_base() now uses pxa_irq_base and just adds an offset.
Hence, there are now no compile-time fixed values used in case of DT
initialization.

Pull OLPC platform updates from Andres Salomon:
"These move the OLPC Embedded Controller driver out of
arch/x86/platform and into drivers/platform/olpc.
OLPC machines are now ARM-based (which means lots of x86 and ARM
changes), but are typically pretty self-contained.. so it makes more
sense to go through a separate OLPC tree after getting the appropriate
review/ACKs."

Pull arm-soc Marvell Orion device-tree updates from Olof Johansson:
"This contains a set of device-tree conversions for Marvell Orion
platforms that were staged early but took a few tries to get the
branch into a format where it was suitable for us to pick up.
Given that most people working on these platforms are hobbyists with
limited time, we were a bit more flexible with merging it even though
it came in late."

Pull arm-soc cpuidle enablement for OMAP from Olof Johansson:
"Coupled cpuidle was meant to merge for 3.5 through Len Brown's tree,
but didn't go in because the pull request ended up rejected. So it
just got merged, and we got this staged branch that enables the
coupled cpuidle code on OMAP.
With a stable git workflow from the other maintainer we could have
staged this earlier, but that wasn't the case so we have had to merge
it late.
The alternative is to hold it off until 3.7 but given that the code is
well-isolated to OMAP and they are eager to see it go in, I didn't
push back hard in that direction."

The only way to write LATCHED registers to write LATCH_BIT to LATCH register,
that will latch COUNTER into LATCHED.e.g.
writel_relaxed(SIRFSOC_TIMER_LATCH_BIT, sirfsoc_timer_base +
SIRFSOC_TIMER_LATCH);
Writing values to LATCHED registers directly is useless at all.

Pull ARM DMA engine updates from Russell King:
"This looks scary at first glance, but what it is is:
- a rework of the sa11x0 DMA engine driver merged during the previous
cycle, to extract a common set of helper functions for DMA engine
implementations.
- conversion of amba-pl08x.c to use these helper functions.
- addition of OMAP DMA engine driver (using these helper functions),
and conversion of some of the OMAP DMA users to use DMA engine.
Nothing in the helper functions is ARM specific, so I hope that other
implementations can consolidate some of their code by making use of
these helpers.
This has been sitting in linux-next most of the merge cycle, and has
been tested by several OMAP folk. I've tested it on sa11x0 platforms,
and given it my best shot on my broken platforms which have the
amba-pl08x controller.
The last point is the addition to feature-removal-schedule.txt, which
will have a merge conflict. Between myself and TI, we're planning to
remove the old TI DMA implementation next year."

Pull irqdomain changes from Grant Likely:
"Round of refactoring and enhancements to irq_domain infrastructure.
This series starts the process of simplifying irqdomain. The ultimate
goal is to merge LEGACY, LINEAR and TREE mappings into a single
system, but had to back off from that after some last minute bugs.
Instead it mainly reorganizes the code and ensures that the reverse
map gets populated when the irq is mapped instead of the first time it
is looked up.
Merging of the irq_domain types is deferred to v3.7
In other news, this series adds helpers for creating static mappings
on a linear or tree mapping."

There's nothing about the debugfs interface for the EC driver that is
architecture-specific, so move it into the arch-independent driver.
The code is mostly unchanged with the exception of renamed variables, coding
style changes, and API updates.

This uses the new EC driver framework in drivers/platform/olpc. The
XO-1 and XO-1.5-specific code is still in arch/x86, but the generic stuff
(including a new workqueue; no more running EC commands with IRQs disabled!)
can be shared with other architectures.

Switch over to using olpc-ec.h in multiple steps, so as not to break builds.
This covers every driver that calls olpc_ec_cmd().

The OLPC EC driver has outgrown arch/x86/platform/. It's time to both
share common code amongst different architectures, as well as move it out
of arch/x86/. The XO-1.75 is ARM-based, and the EC driver shares a lot of
code with the x86 code.

"This patch series contains a major revamp of how we collect entropy
from interrupts for /dev/random and /dev/urandom.
The goal is to addresses weaknesses discussed in the paper "Mining
your Ps and Qs: Detection of Widespread Weak Keys in Network Devices",

vm_stat_account() accounts the shared_vm, stack_vm and reserved_vm now.
But we can also account for total_vm in the vm_stat_account() which makes
the code tidy.
Even for mprotect_fixup(), we can get the right result in the end.
