TIF_NOTIFY_RESUME added (as bit 5). That way nommu glue needs no changes at
all; mmu one needs just to replace jmi do_signal_return to jne do_signal_return
There we have flags shifted up, until bit 6 (SIGPENDING) is in MSBit; instead
of checking that MSBit is set (jmi) we check that MSBit or something below it
is set (jne); bits 0..4 are never set, so that's precisely "bit 6 or bit 5 is
set".
Usual handling of NOTIFY_RESUME/SIGPENDING is done in do_notify_resume(); glue
calls it instead of do_signal().

As described in e6fa16ab ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check whether the signal we're about to block is
pending in the shared queue.
Also, use the new helper function introduced in commit 5e6292c0f28f
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate code
across architectures. In the past some architectures got this code wrong,
so using this helper function should stop that from happening again.

Pull m68knommu tree from Greg Ungerer:
"More merge and clean up of MMU and non-MMU common files, namely
signal.c and dma.c. There is also a simplification of the ColdFire
GPIO setup tables. Using a couple of simple macros we make the init
tables really small and easy to read, and save a couple of thousand
lines of code. Also a move of all the ColdFire subarch support files
into the existing coldfire directory. The sub-directories just ended
up duplicating Makefiles and now only contain really simple pieces of
code. This saves quite a few lines of code too.
As always a couple of bugs fixes thrown in too. Oh and a new
defconfig for the ColdFire platforms that support having the MMU
enabled."

Sigh, I missed to check which architecture Kconfig files actually
include the core Kconfig file. There are a few which did not. So we
broke them.
Instead of adding the includes to those, we are better off to move the
include to init/Kconfig like we did already with irqs and others.
This does not change anything for the architectures using the old
style periodic timer mode. It just solves the build wreckage there.
For those architectures which use the clock events infrastructure it
moves the include of the core Kconfig file to "General setup" which is
a way more logical place than having it at random locations specified
by the architecture specific Kconfigs.

This patch fixes unaligned memory access for the 68000 core based cpu's.
Some time ago, my cpu (68000) was raising address/bus error's when mounting
cifs shares (didn't bother to debug it at the time). After developing the
MMC/SD card driver I was having the same issue when mounting the vfat fs.
I've traced the issue down to the 'unaligned.h' file. (I guess nobody has
ever used unaligned.h back in the 68328 'era'.

The majority of the m68k architecture dma code is the same, so merge the
current separated files dma_no.c and dma_mm.c back into a single dma.c
The main alloc and free routines are a little different, so we keep a
single #ifdef based on CONFIG_MMU for them. All the other support functions
are now identical.

Introduce cache_push() and cache_clear() functions for the non-MMU m68k
devices. With these in place we can more easily merge some of the common
m68k arch code.
In particular by reorganizing the __flush_cache_all() code and separating
the cache push and clear functions it becomes trivial to implement the
new cache_push() and cache_clear() functions.

We have very large tables in the ColdFire CPU GPIO setup code that essentially
boil down to 2 distinct types of GPIO pin initiaization. Using 2 macros we can
reduce these large tables to at most a dozen lines of setup code, and in quite
a few cases a single table entry.
Introduce these 2 macros into the existing mcfgpio.h header.

The MMU (signal_mm.c) and non-MMU (signal_no.c) versions of the m68k
architecture signal handling code are very similar. Most of their code is
the same.
Merge the two back into a single signal.c, and move some of the code around
inside the file to minimize the number of #ifdefs required. Specificially
we can group out the CONFIG_FPU and the CONFIG_MMU code. We end up needing
a few other "#ifdef CONFIG_MMU" as well, but not too many.
