Instead of hardcoding the SYSRAM details for each SoC,
pass this information through device tree (DT) and make
the code SoC agnostic. Generic DT SRAM bindings are
used for achieving this.

If the renamed symbol is defined lib/iomap.c implements ioport_map and
ioport_unmap and currently (nearly) all platforms define the port
accessor functions outb/inb and friend unconditionally. So
HAS_IOPORT_MAP is the better name for this.
Consequently NO_IOPORT is renamed to NO_IOPORT_MAP.
The motivation for this change is to reintroduce a symbol HAS_IOPORT
that signals if outb/int et al are available. I will address that at
least one merge window later though to keep surprises to a minimum and
catch new introductions of (HAS|NO)_IOPORT.
The changes in this commit were done using:
$ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/'

The legacy HAVE_PWM Kconfig symbol is finally being retired. Thanks a

Three new drivers are added: Freescale FTM, Cirrus Logic CLPS711X and
Intel Low Power Subsystem.
An assortment of fixes and cleanups rounds things off for this release

- Support for Cortex-A12 (run perf stat on your FPGA!)
- Support for perf_sample_event_took, allowing us to automatically decrease
the sample rate if we can't handle the PMU interrupts quickly enough
(run perf record on your FPGA!).
- Basic uprobes support from David Long:
This patch series adds basic uprobes support to ARM. It is based on
patches developed earlier by Rabin Vincent. That approach of adding
hooks into the kprobes instruction parsing code was not well received.
This approach separates the ARM instruction parsing code in kprobes out
into a separate set of functions which can be used by both kprobes and
uprobes. Both kprobes and uprobes then provide their own semantic action
tables to process the results of the parsing.
- ARMv7M (microcontroller) updates from Uwe Kleine-König
- OMAP DMA updates (recently added Vinod's Ack even though they've been
sitting in linux-next for a few months) to reduce the reliance of
omap-dma on the code in arch/arm.

Updates to devicetree core code. This branch contains the following notable changes:
* Add reserved memory binding
* Make struct device_node a kobject and remove legacy /proc/device-tree
* ePAPR conformance fixes
* Update in-kernel DTC copy to version v1.4.0
* Preparation changes for dynamic device tree overlays
* minor bug fixes and documentation changes
The most significant change in this branch is the conversion of struct
device_node to be a kobject that is exposed via sysfs and removal of the
old /proc/device-tree code. This simplifies the device tree handling
code and tightens up the lifecycle on device tree nodes.

Moxart uses an FA526 CPU core, which is ARMv4 based, not ARMv4T.
Before moxart, we had no CONFIG_MULTI_V4 option, since no ARMv4 platform
was enabled for multiplatform. This now adds the missing option, which
will give us slightly more efficient code on pure moxart kernels,
because we can build a pure FA526 kernel now rather than a combined
FA526+ARM920T kernel that we used to.

The power domain code is only available when CONFIG_PM

s3c64xx. Changing it to 'select PM_GENERIC_DOMAINS if PM'
mirrors what we do on other platforms, and fixes a possible
randconfig build bug.

so we can make the option implicitly selected by the platform

Currently AUDITSYSCALL has a long list of architecture depencency:
depends on AUDIT && (X86 || PARISC || PPC || S390 || IA64 || UML ||
SPARC64 || SUPERH || (ARM && AEABI && !OABI_COMPAT) || ALPHA)
The purpose of this patch is to replace it with HAVE_ARCH_AUDITSYSCALL

This patch series adds basic uprobes support to ARM. It is based on
patches developed earlier by Rabin Vincent. That approach of adding
hooks into the kprobes instruction parsing code was not well received.
This approach separates the ARM instruction parsing code in kprobes out
into a separate set of functions which can be used by both kprobes and
uprobes. Both kprobes and uprobes then provide their own semantic action
tables to process the results of the parsing.
Using Rabin Vincent's ARM uprobes patches as a base, enable uprobes
support on ARM.
Caveats:
- Thumb is not supported

With noMMU, CONFIG_PAGE_OFFSET was not being set correctly. As there's
no MMU, PAGE_OFFSET should be equal to PHYS_OFFSET in all cases. This
commit makes that explicit.
Since we do this, we don't need to mess around in asm/memory.h with
ifdefs to sort this out, so let's get rid of that, and there's no point
offering the "Memory split" option for noMMU as that's meaningless
there.

Pull Xen bugfixes from Konrad Rzeszutek Wilk:
"Bug-fixes for the new features that were added during this cycle.
There are also two fixes for long-standing issues for which we have a
solution: grant-table operations extra work that was not needed
causing performance issues and the self balloon code was too
aggressive causing OOMs.
Details:
- Xen ARM couldn't use the new FIFO events
- Xen ARM couldn't use the SWIOTLB if compiled as 32-bit with 64-bit PCIe devices.
- Grant table were doing needless M2P operations.
- Ratchet down the self-balloon code so it won't OOM.
- Fix misplaced kfree in Xen PVH error code paths"
* tag 'stable/for-linus-3.14-rc0-late-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
xen/pvh: Fix misplaced kfree from xlated_setup_gnttab_pages
drivers: xen: deaggressive selfballoon driver
xen/grant-table: Avoid m2p_override during mapping
xen/gnttab: Use phys_addr_t to describe the grant frame base address
xen: swiotlb: handle sizeof(dma_addr_t) != sizeof(phys_addr_t)
arm/xen: Initialize event channels earlier
The use of phys_to_machine and machine_to_phys in the phys<=>bus conversions
causes us to lose the top bits of the DMA address if the size of a DMA address is not the same as the size of the phyiscal address.
This can happen in practice on ARM where foreign pages can be above 4GB even
though the local kernel does not have LPAE page tables enabled (which is
totally reasonable if the guest does not itself have >4GB of RAM). In this
case the kernel still maps the foreign pages at a phys addr below 4G (as it
must) but the resulting DMA address (returned by the grant map operation) is
much higher.
This is analogous to a hardware device which has its view of RAM mapped up
high for some reason.
This patch makes I/O to foreign pages (specifically blkif) work on 32-bit ARM
systems with more than 4GB of RAM.

Updates of SoC-near drivers and other driver updates that makes more sense to
take through our tree.
The largest part of this is a conversion of device registration for some
renesas shmobile/sh devices over to use resources. This has required
coordination with the corresponding arch/sh changes, and we've agreed
to merge the arch/sh changes through our tree.
Added in this branch is support for Trusted Foundations secure firmware,
which is what is used on many of the commercial Nvidia Tegra products
that are in the market, including the Nvidia Shield. The code is local
to arch/arm at this time since it's uncertain whether it will be shared
with arm64 longer-term, if needed we will refactor later.
A couple of new RTC drivers used on ARM boards, merged through our tree
on request by the RTC maintainer.
... plus a bunch of smaller updates across the board, gpio conversions
for davinci, etc.

This branch is reducing in size for every release since most board-related
changes have started happening in devicetrees now. Still, we have some things
going on here.
* Renesas platforms are still adding a bit more legacy device support, something
that should trail off shortly as they move to full DT.
* We group most defconfig updates into this branch out of old habits
* Removal of legacy OMAP2 platforms over to DT continues, and a handful of old
code is being removed here.
