commit 69961c3752 ("[PATCH] m68k/Atari:
Interrupt updates") added a BUG_ON() with an incorrect upper bound
comparison, which causes an early crash on VME boards, where IRQ_USER is
8, cnt is 192 and NR_IRQS is 200.

If CONFIG_PROC_FS is not set, I get:
| arch/m68k/kernel/ints.c:433: error: redefinition of 'init_irq_proc'
| include/linux/interrupt.h:438: error: previous definition of 'init_irq_proc' was here
This was introduced by commit 6168a702ab
("Declare init_irq_proc before we use it."), which replaced the #ifdef
protection of the init_irq_proc() call by a static inline dummy if
CONFIG_PROC_FS is not set.
Make init_irq_proc() depend on CONFIG_PROC_FS to fix this.

Now that the last inlined instances are gone, all that is left to do
is turning disable_irq_nosync on arm26 and m68k from defines to aliases
and we are all set - we can make these externs in linux/interrupt.h
uncoditional and kill remaining instances in asm/irq.h

powerpc gets:
init/main.c: In function `do_basic_setup':
init/main.c:714: warning: implicit declaration of function `init_irq_proc'
but we cannot include linux/irq.h in generic code.
Fix it by moving the declaration into linux/interrupt.h instead.
And make sure all code that defines init_irq_proc() is including
linux/interrupt.h.
And nuke an ifdef-in-C

Misc Atari fixes:
- initialize correct number of atari irqs
- silence vbl interrupt until it's used by atafb
- use mdelay() to read clock if necessary

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

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.

Convert the generic irq code to use irq controller, this gets rid of the
machine specific callbacks and gives better control over irq handling without

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!
