If max_pfn is not initialized, the various /proc/kpage* files are empty,
and selftests/vm/mlock2-tests will fail. max_pfn is also used by the
block layer to calculate DMA masks.

Switch from init_bootmem_node() to init_bootmem(), as there's only one
memory node on Sun-3. This will initialize min_low_pfn and max_low_pfn,
which was also not done before.

remove m68k's mach_gettimeoffset function pointer, and instead directly
set the arch_gettimeoffset function pointer. This requires multiplying
all function results by 1000, since the removed m68k_gettimeoffset() did
this. Also, s/unsigned long/u32/ just to make the function prototypes
exactly match that of arch_gettimeoffset.

  - Replace external declarations by proper includes where availiable.
    The accesses to some symbols had to be modified, as before they were
    declared using e.g. "extern int _end", while asm-generic/sections.h uses
    e.g. "extern char _end[]"
  - Remove unused or superfluous external declarations

This patch contains the following possible cleanups:
- make the following needlessly global code static:
  - config.c: sun3_bootmem_alloc()
  - config.c: sun3_sched_init()
  - dvma.c: dvma_page()
  - idprom.c: struct Sun_Machines[]
  - mmu_emu.c: struct ctx_alloc[]
  - sun3dvma.c: iommu_use[]
  - sun3ints.c: led_pattern[]
- remove the unused sbus.c

Use the new typedef for interrupt handler function pointers rather than
actually spelling out the full thing each time.  This was scripted with the
following small shell script:

#!/bin/sh
egrep -nHrl -e 'irqreturn_t[ 	]*[(][*]' $* |
while read i
do
    echo $i
    perl -pi -e 's/irqreturn_t\s*[(]\s*[*]\s*([_a-zA-Z0-9]*)\s*[)]\s*[(]\s*int\s*,\s*void\s*[*]\s*[)]/irq_handler_t \1/g' $i || exit $?
done

Fallout from previous patch:
 - actually add include/asm-m68k/irq_regs.h
 - missed the prototype of sun3_sched_init()

NB: git diff without argumentgs sucks when you've added
some files...

m68k_handle_int() split in two functions: __m68k_handle_int() takes
pt_regs * and does set_irq_regs(); m68k_handle_int() doesn't get pt_regs
*.

Places where we used to call m68k_handle_int() recursively with the same
pt_regs have simply lost the second argument, the rest is switched to
__m68k_handle_int().

The rest of patch is just dropping pt_regs * where needed.

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!
