The m68k core irq code stopped honoring these flags during the irq
restructuring in 2006.

It was used on Apollo only, before its conversion to genirq.

  - Rename m68k_handle_int() to generic_handle_irq(), and drop the unneeded
    asmlinkage,
  - Rename __m68k_handle_int() to do_IRQ().

This is a wrapper around m68k_setup_irq_chip() that discards its dummy
second parameter, to ease the future transition to genirq.

Make it more similar to the genirq version:
  - Add an irq field

Make it more similar to the genirq version:
  - Remove lock (unused as we don't do SMP anyway),
  - Prepend methods with irq_,
  - Make irq_startup() return unsigned int.

It is not machine-specific, but common irq infrastructure.
Also add the missing asmlinkage, to match its definition.

The contents of asm/hardirq.h are pretty strait forward for both the
MMU (hardirq_mm.h) and non-MMU (hardirq_no.h) include files. Merge the
two back into a single file.

It is reasonably strait forward to merge the mmu and non-mmu versions
of irq.h. Most of the defines and structs are not needed on non-mmu.

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.
