f60a557267 m68knommu: define arch_has_single_step() and friends
Towards adding CONFIG_UTRACE support for non-mmu m68k add
arch_has_single_step, and its support functions user_enable_single_step()
and user_disable_single_step().

faa47b4669 m68k: use generic code for ptrace requests
Remove all but PTRACE_{PEEK,POKE}USR and PTRACE_{GET,SET}{REGS,FPREGS}
from arch_ptrace and let the rest be handled by generic code.  Define
PTRACE_SINGLEBLOCK to enable singleblock tracing.

230d1866a9 m68k: merge the non-MMU and MMU versions of ptrace.h
It is trivial to merge the non-MMU and MMU versions of ptrace.h.
Without a single file "make headers_install" is broken for m68k
(since each of the sub-varients of ptrace.h are not installed).

49148020bc m68k,m68knommu: merge header files
Merge header files for m68k and m68knommu to the single location:

    arch/m68k/include/asm

The majority of this patch was the result of the
script that is included in the changelog below.

The script was originally written by Arnd Bergman and
exten by me to cover a few more files.

When the header files differed the script uses the following:

The original m68k file is named <file>_mm.h  [mm for memory manager]
The m68knommu file is named <file>_no.h [no for no memory manager]

The files uses the following include guard:

This include gaurd works as the m68knommu toolchain set
the __uClinux__ symbol - so this should work in userspace too.

Merging the header files for m68k and m68knommu exposes the
(unexpected?) ABI differences thus it is easier to actually
identify these and thus to fix them.

The commit has been build tested with both a m68k and
a m68knommu toolchain - with success.

The commit has also been tested with "make headers_check"
and this patch fixes make headers_check for m68knommu.
