As noticed by Russell King, we were not setting this properly
to the number of entries, but rather the total size.

This results in the core dumping code allocating waayyyy too
much memory.

1) Several exported symbols need extern decls, they are exported
   not for C code but for assembler routines.

2) PAGE_EXEC isn't used, delete

1) set_brkpt() is referenced by nothing and hasn't been used by anyone
   to my knowledge for many many years.  So just delete it.

2) add extern decl for do_sparc64_fault() in asm/pgtable_64.h

As sparse warns, without this struct page pointer subtraction is
extremely expensive, and this is a pretty common operation in
fast paths.

With this define struct page becomes 64 bytes which makes for a
simple subtract and shift, instead of a costly divide or reciprocol
multiply.

Otherwise sparse doesn't work.  The 32 vs. 64 header ifdef
used under arch/sparc/include/asm/ is:

#if defined(__sparc__) && defined(__arch64__)

And that doesn't work for sparse unless we give it __arch64__

These are very similar chips, in fact they are identical in some

So start commonizing code which they can share.  We begin with

It is just used as a parent to encapsulate two PBM objects.

But that layout is only really relevant and necessary for
psycho PCI controllers, which unlike all the others share
a single IOMMU instance between sibling PCI busses.
