d2661c6215 m68k: add support for DMA_BIDIRECTIONAL in dma support functions
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.

f3ff6432dd m68k: fix ColdFire clear cache operation
The code for clearing (invalidating) the ColdFire cache is actually performing
a push operation. Add functions to clear the cache, and fix cache_clear() to
call the appropriate clear cache function.

b60f187fec m68k: use simpler dma_alloc_coherent() for ColdFire CPUs
On all ColdFire platforms (whether MMU enabled or not) we want to use the
simple page based dma_alloc_coherent. We don't want the virtual mapping
version that is used on classic m68k setups. So modify the conditionals
to use the existing simpler dma_alloc_coherent on all ColdFire and non-MMU
builds.

bea8bcb12d m68knommu: Add support for the Coldfire m5441x.
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
FPU, which I don't think should matter to us in the kernel.

eac5794994 m68knommu: refactor Coldfire GPIO not to require GPIOLIB, eliminate mcf_gpio_chips.
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).

higher CPU types. If we use jbsr instead the code will be clean for all

5bd9dd4501 m68k: use some direct calls to ret_from_exception in entry code
The ret_from_excption code is referenced by its function name, or by a label
set at the start of its code. The non-MMU code can share some of this code
if we make direct calls to ret_from_exception instead of the associated label.
The effected function paths are: buserr, trap and ret_from_fork. So change
these to branch directly to ret_from_exception.

5651721ede x86/vsyscall: allow seccomp filter in vsyscall=emulate
If a seccomp filter program is installed, older static binaries and
distributions with older libc implementations (glibc 2.13 and earlier)
that rely on vsyscall use will be terminated regardless of the filter
program policy when executing time, gettimeofday, or getcpu.  This is
only the case when vsyscall emulation is in use (vsyscall=emulate is the
default).

This patch emulates system call entry inside a vsyscall=emulate by
populating regs->ax and regs->orig_ax with the system call number prior
to calling into seccomp such that all seccomp-dependencies function
normally.  Additionally, system call return behavior is emulated in line
with other vsyscall entrypoints for the trace/trap cases.

Commit ca1d72f033 ('PM / Domains: Make it possible to add devices to

power domains and added pm_genpd_dev_need_restore() function which lets
platform core to notify power domain core that the specified device must
be restored (with its runtime_resume() callback) before first use.

This patch adds the pm_genpd_dev_need_restore() call what brings back
the suspend/resume behaviour for the client devices known from the
previous power domain driver (removed by commit 91cfbd4ee0 - 'ARM:
EXYNOS: Hook up power domains to generic power domain infrastructure').
Client device drivers relay on that suspend/resume behaviour, thus this
patch fixes runtime pm operation for client devices.

Move the static inline function setup_jiffies_interrupt() from

callsite.

This allows to remove the inclusion of <asm/hardirq.h> and <linux/irq.h>
