Rather than #define the options manually in the architecture code, add
Kconfig options for them and select them there instead. This also allows
us to select the compat IPC version parsing automatically for platforms
using the old compat IPC interface.

Pull m68knommu arch update from Greg Ungerer:
"Quite a varied set of changes this time.
- A little more merge cleanup, this time the assembler entry code.
- New sub-architecture support for the ColdFire 5251/5253 and 5441x
CPU families.
- Specific clk support code for the ColdFire 520x and 532x CPU
familes.
- Refactoring of the ColdFire GPIO support.
- PCI bus support for some ColdFire CPUS that have PCI hardware (54xx
family). This showed up a few problems with ColdFire cache,
allocating coherent memory and bi-directional DMA support. Fixes
for those too."

The dma cache support functions do not currently support the direction flag
DMA_BIDIRECTIONAL. If a driver passes this direction to dma_map_single or
friends you will get console output like this:
dma_sync_single_for_device: unsupported dir 0
For example when using the Intel e100 ethernet driver on a ColdFire platform
with PCI bus. You will get a stream of these messages coming out.
Modify the dma cache support code adding support for DMA_BIDIRECTIONAL. It is
actioned by doing a cache push operation.

Add support for the Coldfire 5441x (54410/54415/54416/54417/54418). Currently
we only support noMMU mode. It requires the PIT patch posted previously as it
uses the PIT instead of the dma timer as a clock source so we can get all that
GENERIC_CLOCKEVENTS goodness. It also adds some simple clk definitions and
very simple minded power management. The gpio code is tweeked and some
additional devices are added to devices.c. The Makefile uses -mv4e as
apparently, the only difference a v4m (m5441x) and a v4e is the later has a

If we're not connecting external GPIO extenders via i2c or spi or whatever, we
probably don't need GPIOLIB. If we provide an alternate implementation of
the GPIOLIB functions to use when only on-chip GPIO is needed, we can change
ARCH_REQUIRE_GPIOLIB to ARCH_WANTS_OPTIONAL_GPIOLIB so that GPIOLIB becomes
optional.
The downside is that in the GPIOLIB=n case, we lose all error checking done by
gpiolib, ie multiply allocating the gpio, free'ing gpio etc., so that the
only checking that can be done is if we reference a gpio on an external part.
Targets that need the extra error checking can still select GPIOLIB=y.
For the case where GPIOLIB=y, we can simplify the table of gpio chips to use a
single chip, eliminating the tables of chips in the 5xxx.c files. The
original motivation for the definition of multiple chips was to match the way
many of the Coldfire variants defined their gpio as a spare array in memory.
However, all this really gains us is some error checking when we request a
gpio, gpiolib can check that it doesn't fall in one of the holes. If thats
important, I think we can still come up with a better way of accomplishing
that.
Also in this patch is some general cleanup and reorganizing of the gpio header
files (I'm sure I must have had a reason why I sometimes used a prefix of
mcf_gpio and other times mcfgpio but for the life of me I can't think of it
now).

A number of older ColdFire CPU based boards use NS8390 based network
controllers. Most use the Davicom 9008F or the UMC 9008F. This driver
provides the support code to get these devices working on these platforms.
Generally the NS8390 based eth device is direct connected via the general
purpose bus of the ColdFire CPU. So its addressing and interrupt setup is
fixed on each of the different platforms (classic platform setup).
This driver is based on the other drivers/net/ethernet/8390 drivers, and
includes the lib8390.c code. It uses the existing definitions of the
board NS8390 device addresses, interrupts and access types from the
arch/m68k/include/asm/mcf8390.h, but moves the IO access functions into
the driver code and out of that header.

The arch_gettimeoffset() code is included when building for these CPU types,

The fix is simply to conditionally include the arch_gettimeoffset() code on

Pull timer updates from Thomas Gleixner.
Various trivial conflict fixups in arch Kconfig due to addition of
unrelated entries nearby. And one slightly more subtle one for sparc32
(new user of GENERIC_CLOCKEVENTS), fixed up as per Thomas.

Pull first series of signal handling cleanups from Al Viro:
"This is just the first part of the queue (about a half of it);
assorted fixes all over the place in signal handling.
This one ends with all sigsuspend() implementations switched to
generic one (->saved_sigmask-based).
With this, a bunch of assorted old buglets are fixed and most of the
missing bits of NOTIFY_RESUME hookup are in place. Two more fixes sit
in arm and um trees respectively, and there's a couple of broken ones
that need obvious fixes - parisc and avr32 check TIF_NOTIFY_RESUME
only on one of two codepaths; fixes for that will happen in the next
series"

Pull fpu state cleanups from Ingo Molnar:
"This tree streamlines further aspects of FPU handling by eliminating
the prepare_to_copy() complication and moving that logic to
arch_dup_task_struct().
It also fixes the FPU dumps in threaded core dumps, removes and old
(and now invalid) assumption plus micro-optimizes the exit path by
avoiding an FPU save for dead tasks."
Fixed up trivial add-add conflict in arch/sh/kernel/process.c that came
in because we now do the FPU handling in arch_dup_task_struct() rather
than the legacy (and now gone) prepare_to_copy().
* 'x86-fpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86, fpu: drop the fpu state during thread exit

fork: move the real prepare_to_copy() users to arch_dup_task_struct()
Pull trivial updates from Jiri Kosina:

documentation updates."
