Chestnut43, Gallop43 and Palo43 expansion boards have a ZIF connector
for a 4.3'' LCD. Add a common include file for this configuration, and
use it on relevant expansion boards.

Looks like quite a few omap3 boards have sharp ls037v7dw01 that's
configured as various panel dpi entries for whatever legacy reasons.
For device tree based support, let's just configure these properly for
panel ls037v7dw01 instead of panel dpi.
This patch creates a common file for panel ls037v7dw01, and makes
boards ldp and omap3-evm to use it.
The ls037v7dw01 also seems to be coupled with an ad7846 touchscreen
controller for the omaps, so let's add a basic configuration for
the touchscreen also using the default values.

Pull ARM SoC driver changes from Olof Johansson:
"SoC-near driver changes that we're merging through our tree. Mostly
because they depend on other changes we have staged, but in some cases
because the driver maintainers preferred that we did it this way.
This contains a largeish cleanup series of the omap_l3_noc bus driver,
cpuidle rework for Exynos, some reset driver conversions and a long
branch of TI EDMA fixes and cleanups, with more to come next release.
The TI EDMA cleanups is a shared branch with the dmaengine tree, with
a handful of Davinci-specific fixes on top.
After discussion at last year's KS (and some more on the mailing
lists), we are here adding a drivers/soc directory. The purpose of
this is to keep per-vendor shared code that's needed by different
drivers but that doesn't fit into the MFD (nor drivers/platform)
model. We expect to keep merging contents for this hierarchy through
arm-soc so we can keep an eye on what the vendors keep adding here and
not making it a free-for-all to shove in crazy stuff"

Pull ARM SoC board support updates from Olof Johansson:
"The bulk of this branch is updates for Renesas Shmobile. They are
still doing some enablement for classic boards first, and then come up
with DT bindings when they've had a chance to learn more about the
hardware. Not necessarily a bad way to go about it, and they're
looking at moving some of the temporary board code resulting from it
to drivers/staging instead to avoid the churn here.
As a result of the shmobile clock cleanups, we end up merging quite a
bit of SH code here as well. We ended up merging it here instead of
in the cleanup branch due to the other board changes depending on it"

Pull part one of ARM SoC updates from Olof Johansson:
"A quite large set of SoC updates this cycle. In no particular order:
- Multi-cluster power management for Samsung Exynos, adding support
for big.LITTLE CPU switching on EXYNOS5
- SMP support for Marvell Armada 375 and 38x
- SMP rework on Allwinner A31
- Xilinx Zynq support for SOC_BUS, big endian
- Marvell orion5x platform cleanup, modernizing the implementation
and moving to DT.
- _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so
that their platform can be enabled in the same kernel binary as
most of the other v7 platforms in the tree. \o/
The work isn't quite complete, there's some driver fixes still
needed, but the basics now work.
New SoC support added:
- Freescale i.MX6SX
- LSI Axxia AXM55xx SoCs
- Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800

For ioremapped efi memory aka old_map the virt addresses are not persistant
across kexec reboot. kexec-tools will read the runtime maps from sysfs then
pass them to 2nd kernel and assuming kexec efi boot is ok. This will cause
kexec boot failure.
To address this issue do not export runtime maps in case efi old_map so
userspace can use no efi boot instead.

Fix a long standing bug where, for ARMv6+, we don't fully ensure that
the C code sets the same cache policy as the assembly code. This was
introduced partially by commit 11179d8ca28d ([ARM] 4497/1: Only allow
safe cache configurations on ARMv6 and later) and also by adding SMP
support.
This patch sets the default cache policy based on the flags used by the
assembly code, and then ensures that when a cache policy command line
argument is used, we verify that on ARMv6, it matches the initial setup.

This patch finally allows us to get rid of the BPF_S_* enum.
Currently, the code performs unnecessary encode and decode
workarounds in seccomp and filter migration itself when a filter
is being attached in order to overcome BPF_S_* encoding which
is not used anymore by the new interpreter resp. JIT compilers.
Keeping it around would mean that also in future we would need
to extend and maintain this enum and related encoders/decoders.
We can get rid of all that and save us these operations during
filter attaching. Naturally, also JIT compilers need to be updated
by this.
Before JIT conversion is being done, each compiler checks if A
is being loaded at startup to obtain information if it needs to
emit instructions to clear A first. Since BPF extensions are a
subset of BPF_LD | BPF_{W,H,B} | BPF_ABS variants, case statements
for extensions can be removed at that point. To ease and minimalize
code changes in the classic JITs, we have introduced bpf_anc_helper().
Tested with test_bpf on x86_64 (JIT, int), s390x (JIT, int),
arm (JIT, int), i368 (int), ppc64 (JIT, int); for sparc we
unfortunately didn't have access, but changes are analogous to
the rest.

Due to a design incompatibility between the PCIe Marvell controller
and the Cortex-A9, stressing PCIe devices with a lot of traffic
quickly causes a deadlock.
One part of the workaround for this is to have all PCIe regions mapped
as strongly-ordered (MT_UNCACHED) instead of the default
MT_DEVICE. While the arch_ioremap_caller() mechanism allows
sub-architecture code to override ioremap(), used to map PCIe memory
regions, there isn't such a mechanism to override the behavior of
pci_ioremap_io().
This commit adds the arch_pci_ioremap_mem_type variable, initialized
to MT_DEVICE by default, and that sub-architecture code can
override. We have chosen to expose a single variable rather than
offering the possibility of overriding the entire pci_ioremap_io(),
because implementing pci_ioremap_io() requires calling functions
(get_mem_type()) that are private to the arch/arm/mm/ code.

Make it a little clearer what the littleendian access macros in
vdso2c.[ch] actually do. This way they can probably also be moved to
a central location (e.g. tools/include) for the benefit of other host
tools.
We should avoid implementation namespace symbols when writing code
that is compiling for the compiler host, so avoid names starting with
double underscore or underscore-capital.
