The WakeupM3 remote processor device node has been moved to
be a child node of the newly created l4_wkup node, to reflect
its presence properly within the SoC. The node was added
previously before any driver support, it is now updated as
per the wkup_m3_rproc bindings added alongside the driver
support.

A fairly random colletion of fixes based on -rc1 for OMAP, sunxi and
prima2 as well as a few arm64-specific DT fixes.
This series also includes a late to support a new Allwinner (sunxi)
SoC, but since it's rather simple and isolated to the
platform-specific code, it's included it for this -rc.

We don't want GCC optimising our memset_io(), memcpy_fromio() or
memcpy_toio() variants, so we must not call one of the standard
functions. Provide a separate name for our assembly memcpy() and
memset() functions, and use that instead, thereby bypassing GCC's
ability to optimise these operations.
GCCs optimisation may introduce unaligned accesses which are invalid
for device mappings.

Convert the ioremap*() preprocessor macros to real functions, moving
them out of line. This allows us to kill off __arm_ioremap(), and
__arm_iounmap() helpers, and remove __arm_ioremap_pfn_caller() from
global view.
Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
ioremap_wt() was added by aliasing it to ioremap_nocache(), which is a
device mapping. Device mappings do not allow unaligned accesses, but
it appears that GCC is able to inline its own memcpy() implementation
which may use such accesses. The only user of this is pmem, which
uses memcpy() on the region.
Therefore, this is unsafe. We must implement ioremap_wt() correctly
for ARM, or not at all.
This patch adds a more correct implementation by re-using ioremap_wc()
to provide a normal-memory non-cacheable mapping.

Pull init.h/module.h fragility fixes from Paul Gortmaker:
"Fixup various init.h misuses that are fragile wrt code moving to
module.h
What started as a removal of no longer required include <linux/init.h>
due to the earlier __cpuinit and __devinit removal led to the
observation that some module specfic support was living in init.h
itself, thus preventing the full removal from introducing compile
regressions.
This series includes a few final fixups needed prior to the relocation
of the modular init code from <init.h> to <module.h>. These are
things that weren't easily categorized into any of the other previous
series categories already requested for pull.
That said, each fixup branch (including this one) is independent and
there are no ordering constraints. Only the final code relocation
(which is NOT in this pull) requires that all my cleanup branches be
merged first"

Pull module_init replacement part one from Paul Gortmaker:
"Replace module_init with equivalent device_initcall in non modules.
This series of commits converts non-modular code that is using the
module_init() call to hook itself into the system to instead use
device_initcall().
The conversion is a runtime no-op, since module_init actually becomes
__initcall in the non-modular case, and that in turn gets mapped onto
device_initcall. A couple files show a larger negative diffstat,
representing ones that had a module_exit function that we remove here
vs previously relying on the linker to dispose of it.
We make this conversion now, so that we can relocate module_init from
init.h into module.h in the future.
The files changed here are just limited to those that would otherwise
have to add module.h to obviously non-modular code, in order to avoid
a compile fail, as testing has shown"

Merge tag 'cpuinit-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux
Pull __cpuinit removal from Paul Gortmaker:
"Remove __cpuinit macros and users.
We removed the __cpuinit stuff in 3.11-rc1 with commit 22f0a27367
("init.h: remove __cpuinit sections from the kernel") but we left some
no-op stubs as a courtesy to unmerged code.
Here we get rid of the stubs as well, since (as can be seen in these
changes) they are enabling use cases to sneak back in, primarily from
older BSP code that has been living out of tree for some time prior to
getting mainlined. So we get rid of these "new" users 1st and then
get rid of the stubs.
Obviously, getting rid of the stubs can't happen until all the users
are gone, so I had to keep this together as a series, even though some
of these commits since got picked up into maintainers trees as well.
The nature of this change is such that it should have zero impact on
the generated runtime.
This is one of several independent cleanup branches aimed at enabling
better organization in the init.h and module.h code. They have been
getting coverage in the linux-next tree for the last month, in
addition to my local testing, which also covers approximately a half
dozen or more architectures"

wake IRQ events for omap_hsmmc, 8250_omap and omap-serial

The generic wake IRQs also fix issues that these drivers potentially
have with IRQ re-entrancy at least for serial-omap.
Note that because of dependencies and merge conflicts these are
based on Rafael's pm-wakeirq and Greg's tty-next branches.
