There's a problem with the REQ_BLOCK_PC handling as well (bad ->data_len
handling) where it could actually complete a request ahead of time. I
suggest we just back this out for now, I will resubmit it later when I'm
fully confident in it.

This is part of a patch from Marc Singer to allow r2 to be
passed to the kernel. Marc's original comments follow:
This revised R2 (atags pointer) patch incorporates comments from Nico
Pitre and Ben Dooks. It modifies the head.S files such that the R2
value set by the bootloader is conveyed to the kernel startup code.
The kernel head.S heuristically validates the pointer. It will set R2
to zero if it believes the pointer is invalid. Presently, it requires
that the ATAGS list reside in the first 16KiB of physical RAM.
Relaxing this contraint may be both desirable as well as tricky.

we always set ->SCp.ptr to physical address of buffer; for DMA that's
just what we need, but we end up using it as virtual address in PIO
case of esp_do_data(), with obvious breakage as soon as memory mapping
becomes non-trivial. The fix is obvious.

sound/oss/dmasound/dmasound_atari.c has static expand_bal
sound/oss/dmasound/dmasound_q40.c has static expand_bal
sound/oss/dmasound/dmasound_awacs.c has non-static expand_bal
sound/oss/dmasound/trans_16.c uses expand_bal from dmasound_awacs.c
all 4 include dmasound.h; extern for expand_bal used to be there,
which is a bloody bad idea, considering _atari and _q40. Moved the
extern to trans_16.c.

Too permissive constraint on mulu.l - the first argument should not be
an a-register. Fixed by replacing "g" with "dm"; with older gcc we got
lucky and it had never attempted mulu.l %a0, %d1:%d0. These days it
does, with predictable objections from as(1).

oktagon_esp is described as modular. However, drivers/scsi/Makefile doesn't
handle it right - it's multi-object module, with one of the parts being built
from .S. Current makefile tries to declare each part a module of its own;
that not only wouldn't work (oktagon_io.o doesn't have the right parts for
that), it actually doesn't even build since kbuild doesn't believe in
single-object modules built from .S. Turned into proper multi-object
module...

move the sanity check for NR_IRQS being no more than 1<<HARDIRQ_BITS from
asm-m68k/hardirq.h to asm-m68k/irq.h; needed since NR_IRQS is not necessary
know at the points of inclusion of asm/hardirq.h due to the rather ugly header
dependencies on m68k. Fix is by far simpler than trying to massage those
dependencies...
