There is no reason not to put all RAM in ZONE_DMA for these simple
m68k varients (same as the standard MMU m68k code does). With this
in place the usual dma_alloc_coherent() work as expected.

Remove arch-specific show_mem() in favor of the generic version.
This also removes the following redundant information display:
- free pages, printed by show_free_areas()
- pages in swapcache, printed by show_swap_cache_info()
where show_mem() calls show_free_areas(), which calls
show_swap_cache_info().

Remove is_in_rom() function. It doesn't actually serve the purpose it was
intended to. If you look at the use of it _access_ok() (which is the only use
of it) then it is obvious that most of memory is marked as access_ok. No
point having is_in_rom() then, so remove it.

Remove cache management cruft. This code is dead, all the cache manangement
functions for the ColdFire exist in the header file

Fix array initialization in lots of arches
The number of zones may now be reduced from 4 to 2 for many arches. Fix the
array initialization for the zones array for all architectures so that it is
not initializing a fixed number of elements.

Remove use of rom_length. It serves not real purpose, and when we move
to new stye RAM configuration it will not be needed.

set_page_count usage outside mm/ is limited to setting the refcount to 1.
Remove set_page_count from outside mm/, and replace those users with
init_page_count() and set_page_refcounted().
This allows more debug checking, and tighter control on how code is allowed
to play around with page->_count.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
