Re: [uClinux-dev] [PATCH] m68k: merge the MMU and non-MMU signal.c code

The MMU (signal_mm.c) and non-MMU (signal_no.c) versions of the m68k
architecture signal handling code are very similar. Most of there 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.

Re: [uClinux-dev] [PATCH 2/2] m68k: merge the MMU and non-MMU versions of the arch dma code

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.

Re: [uClinux-dev] [PATCH v2 2/3] m68k: use jbsr to call functions instead of bsrl
On Fri, May 18, 2012 at 6:22 AM, g...@snapgear.com wrote:
From: Greg Ungerer g...@uclinux.org
There is a few places that the m68k entry code uses the bsrl instruction
to call other functions. That instruction is only supported on 68020 and
higher CPU types. If we use jbsr instead the code will be clean for all
68k and ColdFire CPU types.

Re: [uClinux-dev] [PATCH v2 1/3] m68k: use some direct calls to ret_from_exception in entry code
On Fri, May 18, 2012 at 6:22 AM, g...@snapgear.com wrote:
From: Greg Ungerer g...@uclinux.org
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.

Some of the entry.S code is common to both MMU and non-MMU builds.
So merge the entry_no.S and entry_mm.S files back into a single file.
With a little code movement we only need a single #ifdef.
