    ARM: 8042/1: iwmmxt: allow to build iWMMXt on Marvell PJ4B

fixed the error that prevented Dove SoC from being built with
the rest of the mvebu SoCs, we can now add it to the defconfig.

In addition, this commit enables SERIAL_OF_PLATFORM, which is required
to have UART on some of the boards.

The System Type menu is getting quite long with platforms and is
inconsistent in handling of sub-arch specific options. Tidy up the menu

Following 5d01b768 "mmc: simplify SDHCI Kconfig dependencies",
SDHCI drivers that use MMC_SDHCI_PLTFM no longer select it, but
instead depend on it. This means that multi_v7_defconfig no longer
selects it, and hence many SDHCI drivers are no longer enabled.
Explicitly enable MMC_SDHCI_PLTFM to solve this.

This solves a problem with building with CONFIG_SMP=n due to missing
sysram_base_addr (or sysram_ns_base_addr) variables.

The new setup method is more awkward than I'd like for it to be, but
it can't be done in init_early() since ioremap is not yet available,
but it needs to happen before SMP.

The addition of Exynos to multi-platform configs creates a mess of config
options with options appearing before the Exynos config option. This is
due to arch/arm/plat-samsung/Kconfig being included out of order with the
other Samsung platform kconfig files. Reorder the kconfig files and move
all the options into a sub-menu. Some of the options are dead, so remove
those as well.

This config exists entirely to hide the cpufreq menu from the
kernel configuration unless a platform has selected it. Nothing
is actually built if this config is 'Y' and it just leads to more
patches that add a select under a platform Kconfig so that some
other CPUfreq option can be chosen. Let's remove the option so
that we can always enable CPUfreq drivers on ARM platforms.

This addresses a section mismatch problem in the IM-PD1
driver in the Integrator/AP.

The IM-PD1 contains a VIC interrupt controller and therefore
the driver calls vic_init_cascaded() which is marked __init as
irqchips are simply not hot-pluggable and specifically the VIC
is assumed to initiate only on boot.

However the module driver model of the Integrator LM bus
assumes that logic tile drivers can be probed at runtime. This
is not really the case for IM-PD1: these tiles are detected at
boot and they cannot be plugged into a running system. Before
this patch it is of course possible to modprobe them later.

By first forcing the IM-PD1 to bool we make sure this driver
gets compiled into the kernel, and we know it will be probed
only at boot time when the tiles are detected, so we can tag
its probe function __init_refok as we know it won't be called
after boot now, and the section mismatch problem goes away.

As a side effect, sysfs binding from userspace becomes
impossible, so we tag the driver to suppress the bind/unbind
sysfs attributes.

The only remaining driver using the samsung dmadev code is the broken
samsung-ac97 sound driver. However, as found by Russell's autobuilder,
the elaborate dependency chains around it cause problems with
circular dependencies.

This is an attempt to simplify those dependencies by making the
SAMSUNG_DMADEV option user-selectable. I also try to keep the
default settings for all related options unchanged, so we don't
introduce any regressions against earlier testing on linux-next.

In particular, all s3c64xx and s5p* platforms keep selecting the
pl330 and pl08x drivers they require, but the select statement
is now moved towards the main platform option, and it remains
optional by unselecting CONFIG_DMADEVICES.

We can only use CMA on systems that have an MMU, because of
the requirement to use memory migration. NOMMU systems are
rather constrained to start with, but it seems reasonable
to assume that DMA allocations can still succeed in the
constrained case for remoteproc on NOMMU, so this patch
changes the da8xx implementation to not rely on CMA when
the MMU is disabled.

The arm-cci code uses device tree helpers for initialization
that don't work on kernels built without CONFIG_OF. Further,
it contains an inline assembly in cci_enable_port_for_self()
that uses ARMv7 instructions and fails to build when targetting
other ARM instruction set versions.

This works around both issues by limiting the scope of the
Kconfig symbol to platforms that can actually build this driver
cleanly.

The dynamic relocation that the keystone platform performs
only works if we can pick the phys offset at boot time. It's
possible that there is another solution for this, but this
is the easiest workaround. Kernels with ARM_PATCH_PHYS_VIRT
are not portable across platforms, and I see no reason why
anyone would run a kernel without ARM_PATCH_PHYS_VIRT on
keystone.

Commit d941f86f ("ARM: l2c: AM43x: add L2 cache support") enabled
the L2 cache support for the am43xx SoC, but caused a build regression
when the driver for that cache controller is disabled:

arch/arm/mach-omap2/built-in.o: In function `am43xx_init_early':
:(.init.text+0xb20): undefined reference to `omap_l2_cache_init'

This did not happen for OMAP4, which has the same call, but enables
the l2x0 driver unconditionally. We could do the same thing for
am43xx, but it seems better to allow turning it off and make the
code work in either case.

This adds an inline wrapper for omap_l2_cache_init for the disabled
case, and removes the 'select' from OMAP4 so it becomes a user
visible option.

Pull powerpc updates from Ben Herrenschmidt:
 "Here is the bulk of the powerpc changes for this merge window.  It got
  a bit delayed in part because I wasn't paying attention, and in part
  because I discovered I had a core PCI change without a PCI maintainer
  ack in it.  Bjorn eventually agreed it was ok to merge it though we'll
  probably improve it later and I didn't want to rebase to add his ack.

  There is going to be a bit more next week, essentially fixes that I
  still want to sort through and test.

  The biggest item this time is the support to build the ppc64 LE kernel
  with our new v2 ABI.  We previously supported v2 userspace but the
  kernel itself was a tougher nut to crack.  This is now sorted mostly
  thanks to Anton and Rusty.

  We also have a fairly big series from Cedric that add support for
  64-bit LE zImage boot wrapper.  This was made harder by the fact that
  traditionally our zImage wrapper was always 32-bit, but our new LE
  toolchains don't really support 32-bit anymore (it's somewhat there
  but not really "supported") so we didn't want to rely on it.  This
  meant more churn that just endian fixes.

  This brings some more LE bits as well, such as the ability to run in
  LE mode without a hypervisor (ie. under OPAL firmware) by doing the
  right OPAL call to reinitialize the CPU to take HV interrupts in the
  right mode and the usual pile of endian fixes.

  There's another series from Gavin adding EEH improvements (one day we
  *will* have a release with less than 20 EEH patches, I promise!).

  Another highlight is the support for the "Split core" functionality on
  P8 by Michael.  This allows a P8 core to be split into "sub cores" of
  4 threads which allows the subcores to run different guests under KVM
  (the HW still doesn't support a partition per thread).

  And then the usual misc bits and fixes ..."

 "Very little of excitement here - the most significant is a new driver
  for detecting device freefall on Dells, other than that it's pretty
  much entirely minor fixes for specific machines"

This is a third attempt to enable these buttons. The new variable being
commit 997daa1b (i.e. hp-wmi: detect
"2009 BIOS or later"). Older systems that do not have the 2009 BIOS query
method respond with a dummy value, in this case 4. Using that, we can
target a fairly narrow group of systems. i.e. old enough to not have
HPWMI_FEATURE_QUERY 0xd, but new enough to have HPWMI_BIOS_QUERY 0x9.
This group may be further limited if some systems respond with something
other than 4 to non-existant feature queries.

The T440s user guide says that when Fn-lock is not active, the *40s' F9 - F12
keys should be mapped to: control-panel, search, show-all-windows and Computer.

These keys generate the sofar unused 28 - 31 hotkey scancodes.

For the first 2 this nicely matches the icons on the keys, for the latter 2
the icons are somewhat creative, which is why I ended up looking them up in
the user manual.

This acpi driver provide supports for freefall sensors SMO8800/SMO8810 which
can be found on Dell Latitude laptops. Driver register /dev/freefall misc
device which has same interface as driver hp_accel freefall driver. So any
existing applications for HP freefall sensor /dev/freefall will work for with
this new driver for Dell Latitude laptops too.

This patch moves data allocated using kzalloc to managed data allocated
using devm_kzalloc and cleans now unnecessary kfrees in probe and remove
functions. The label sysfs_failed is removed as it is no longer
required.  Also, linux/device.h is added to make sure the devm_*()
routine declarations are unambiguously available.

The following Coccinelle semantic patch was used for making the change:

  .probe = probefn,
  .remove = removefn,

The Lenovo Yoga 2 11 always reports everything as blocked, causing userspace
to not even try to use the wlan / bluetooth even though they work fine.

Note this patch also removes the "else priv->rfk[i] = NULL;" bit of the
rfkill initialization, it is not necessary as the priv struct is allocated
with kzalloc.
