Reduce the function pointer mess of the m68knommu timer code by calling
directly to the local hardware's timer setup, and expose the local
common timer interrupt handler to the lower level hardware timer.
Ultimately this will save definitions of all these functions across all
the platform code to setup the function pointers (which for any given
m68knommu CPU family member can be only one set of hardware timer
functions).

A new style serial driver for the Freescale ColdFire UART to replace
the old style one currently in the tree (drivers/serial/mcfserial.c).
Currently this UART is only found in the ColdFire CPU family of parts
(thus I prefixed this patch [M68KNOMMU]).
This has been around for a long while now, tested on all available
platforms.

Up to now m68knommu has been using the asm-m68k/module.h instead of
defining its own. There are recent changes there that we don't need
(fixups specifically). We don't need much support here so it makes
sense to have an m68knommu specific one now.

ops_complete_biofill() runs outside of spin_lock(&sh->lock) and clears the

against 'complete' it can get an inconsistent snapshot of pending work.
Move the clearing of these bits to handle_stripe5(), under the lock.

Commit 4f9a58d75b ("increase
AT_VECTOR_SIZE to terminate saved_auxv properly") changes the size of
AT_VECTOR_SIZE from hard coded '44' to a calculation based on the value
of AT_VECTOR_SIZE_ARCH and AT_VECTOR_SIZE_BASE.
The change works for arch/powerpc, but it breaks arch/ppc because the
needed AT_VECTOR_SIZE_ARCH is not present in include/asm-ppc/system.h
and a default value of 0 is used instead. This results in
AT_VECTOR_SIZE being too small and it causes a kernel crash on loading
init.

The BCM148 has 4 cores but there are also just 4 generic timers available
so use the ZBbus cycle counter instead of it. In addition the ZBbus
counter also offers a much higher resolution and 64-bit counting so I'm
considering a later complete conversion to it once I figure out if all
members of the Sibyte SOC family support it - the docs seem to agree but
the headers files seem to disagree ...

Change the page member of the scatterlist structure to be an unsigned
long, and encode more stuff in the lower bits:
- Bits 0 and 1 zero: this is a normal sg entry. Next sg entry is located
at sg + 1.
- Bit 0 set: this is a chain entry, the next real entry is at ->page_link
with the two low bits masked off.
- Bit 1 set: this is the final entry in the sg entry. sg_next() will return
NULL when passed such an entry.
It's thus important that sg table users use the proper accessors to get
and set the page member.
