The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications. For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.
After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out. Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.
Note that some harmless section mismatch warnings may result, since
notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
and are flagged as __cpuinit -- so if we remove the __cpuinit from
the arch specific callers, we will also get section mismatch warnings.
As an intermediate step, we intend to turn the linux/init.h cpuinit
related content into no-ops as early as possible, since that will get
rid of these warnings. In any case, they are temporary and harmless.
This removes all the ARM uses of the __cpuinit macros from C code,
and all __CPUINIT from assembly code. It also had two ".previous"
section statements that were paired off against __CPUINIT
(aka .section ".cpuinit.text") that also get removed here.

These are changes that arrived a little late before the merge
window or that have multiple dependencies on previous branches
so they did not fit into one of the earlier ones. There
are 10 branches merged here, a total of 39 non-merge commits.
Contents are a mixed bag for the above reasons:
* Two new SoC platforms: ST microelectronics stixxxx and
the TI 'Nspire' graphing calculator. These should have
been in the 'soc' branch but were a little late
* Support for the Exynos 5420 variant in mach-exynos,
which is based on the other exynos branches to avoid
conflicts.
* Various small changes for sh-mobile, ux500 and davinci
* Common clk support for MSM
Conflicts:
* In Kconfig.debug, various additions trivially conflict,

These changes are all driver specific and cross over between arm-soc
contents and some other subsystem, in these cases cpufreq, crypto,
dma, pinctrl, mailbox and usb, and the subsystem owners agreed to
have these changes merged through arm-soc. As we proceed to untangle
the dependencies between platform code and driver code, the amount of
changes in this category is fortunately shrinking, for 3.11 we have
16 branches here and 101 non-merge changesets, the majority of which
are for the stedma40 dma engine driver used in the ux500 platform.
Cleaning up that code touches multiple subsystems, but gets rid
of the dependency in the end.
The mailbox code moved out from mach-omap2 to drivers/mailbox
is an intermediate step and is still omap specific at the moment.
Patches exist to generalize the subsystem and add other drivers
with the same API, but those did not make it for 3.11.
Conflicts:
* In cpu-db8500.c results from the removal of the u8500_of_init_devices
function in combination with the split of u8500_auxdata_lookup.
* In arch/arm/mach-omap2/devices.c, the includes got reshuffled.
we need to keep linux/wl12xx.h and linux/platform_data/mailbox-omap.h.

These changes from 30 individual branches for the most part update device
tree files, but there are also a few source code changes that have crept
in this time, usually in order to atomically move over a driver from
using hardcoded data to DT probing.
A number of platforms change their DT files to use the C preprocessor,
which is causing a bit of churn, but that is hopefully only this once.
There are a few conflicts with the other branches unfortunately:
* in exynos5440.dtsi and kirkwood-6281.dtsi, device nodes are added
from multiple branches. Need to be careful to have the right
set of closing braces as git gets this one wrong.
* In kirkwood.dtsi, one 'ranges' line got split into two lines, while
another line got added. Order of the lines does not matter.
* in sama5d3.dtsi, some cleanup was merged the wrong way, causing
a bogus conflict. We want the 'dmas' and 'dma-names' properties
to get added here.
* Two lines got removed independently in arch/arm/mach-mxs/mach-mxs.c
* Contents get added independently in arch/arm/mach-omap2/cclock33xx_data.c

mop500_snowball_ethernet_clock_enable() provided a means to enable a

This patch fixes a bug introduced in the v3.10 merge window.
The AB8500 External Regulator driver has recently landed upstream,
which registers each of the 3 external regulators located on the
AB8500. If these regulators are marked as 'always on', there is a
potential for power-loss. If they're not and are seemingly unused
the Regulator subsystem will attempt to disable them to save power.
This causes an issue for AUX1, AUX2 and AUX3 as they obtain their
power from EXT3. So we're specifying that here to prevent EXT3 from
being powered down.

Multiplatform calls all enabled platforms' initcalls. In the
ux500_idle_init() initcall we call into the DBx500-PRCMU which in turn
executes some ux500 specific register reads/writes. When running on
some !ux500 platforms this ends up causing a kernel Oops. This patch
ensures the PRCMU call is only invoked when running on ux500 based
platforms.

Ironically, in order to remove lots of the auxdata assignments, we have
to add just one more. A lot of them require DMA information to be passed
into clients for DMA channel allocation, but we now have this capability
in Device Tree. However, the DMA40 driver still relies on a reverse table
look-up to obtain DMA addresses. Until all of the clients are converted,
over to the new API, we're stuck with this.
Also, now the DMA40 has been DT:ed, there's no requirement to register
it using traditional methods, so let's remove it.
