awful code with loops

We have a fair number of command line options which can be used
to pass information about the target to the kernel.  We also provide
a default command line which the kernel will use in absence of one
provided by the boot loader.  We pass the hard coded options via the
command line now.

atomic.h was generating some extra loads that aren't required.  In
addition, it was needlessly performing various tests inside the
atomic region.  This change fixes both these issues.

 - We don't need to save the CPSR.
 - Rearrange thread_info members so we can pull the fields out of
   thread_info more efficiently.
 - Allocate a couple of extra words for CPU specific context saving
   (eg, for Xscale ACC registers)
 - Always leave 8 bytes free at the top of the kernel stack.  This
   prevents the stack becoming completely empty when do_exit() is
   called from an exiting nfsd() thread, and causing the wrong
   pointer to be returned from current_thread_info()

This machine type is no longer maintained and is falling into bitrot
heaven.

1) Eliminate everywhere "if (0 == result)" is used, replace with
"if (!result)" and the like.

2) Move headers mysteriously included in the middle of the file to the top.

(where they clearly didn't belong) into arch/asm/acpi.h

drivers/base/bus.c and drivers/pci/pci-driver.c both have functions
which are marked with __init, but didn't include <linux/init.h> directly.
The following fixes that (and allows 2.5.19 to compile on PPC32).

bug: array of u32 is accessed with offset in u8 units.

We now can boot without MPS and PIRQ!
ACPI finds IO APICs, Local apics (CPUS), interrupt source overrides,
the works. (Paul Diefenbaugh) Mucho thanks to Dominik Brodowski and
the whole acpi-devel gang.

(Note, I think this conflicts slightly with Pavel's code in i386/kernel/acpi.c
but I'd like to get this applied, and then I'm working with Pavel to hopefully
get the ACPI and swsusp stuff working properly.)

de4x5.c used struct bus_type for its internal bookkeeping. It should
be proably converted to struct device, but as I prefer
Jeff's tulip driver, and I have no knowledge about EISA support,
I only changed the structure name to make thing compile.

The following fixes compilation with CONFIG_BLK_DEV_RAM=y I assume that
Rusty intended to use a test for CONFIG_BLK_DEV_RAM and not
BLOCK_DEV_RAM.

Improved error checking on hw accesses
Moved arch specific macros to arch/asm/acpi.h
