Patch from Ben Dooks

If we read the INTPEND register and get the wrong
result (details below) then it looks like a possible
loop to go back and re-read it after calculating
the possible correct value for it.

It seems that the INTPEND register, which should
show the unique number of the interrupt that we
need to handle. However, it seems that this register
can show the wrong interrupt under certain conditions.

Shannon's research shows that it is very possible that
the occurence of an external interrupt can end up
merging with the base interrupt number, causing
the wrong result in the register.

This patch also fixes the end position of the #ifdef
block and ensures as many registers as possible are
stacked before calling printk() for debug.

Original patch for 2.6.9 by Shannon Holland re-written
for 2.6.10 by Ben Dooks.

Patch from Ben Dooks

This is an old definition, and is no longer used anywhere.
Add a comment to that effect in the header file
include/asm-arm/arch-s3c2410/timex.h and remove all other
references.

Thanks to Klaus Fetscher for pointing out that it isn't
used anymore

Here is a patch to provide faster bitops for m68knommu, using bset/bclr/bchg
and btst instructions, that do test-and-set on m68k and coldfire processors.
We do thus avoid the need for local_irq_save/local_irq_restore.

Patch from Nicolas Pitre

Those defines are incomplete and not using them by
instead using the explicit flags makes for clearer code.

Essentially, this set of changes:
1. makes the register usage in head.S more sane
2. makes way for passing the location of the tagged list via "r2"
   (as the booting document suggests)

This brings the latency back to previous levels, and in
fact seems to drive it a bit lower.

There were a few variants on the list trying to work out what the valid
ranges to verify for write are but they sort of missed the point, if you
can load new firmware you can have fun anyway.

IN_STRING_C was an i386-specific hack by Andi Kleen to provide out-of-line
versions of some lib/string.c functions that aren't directly used on i386
(because there are inline assembly versions).

This can cause problems if gcc chooses to transparently replace a call to one
string function with a call to another string function (the example Andi gave
was a replacement of a sprintf call with a strcpy call) which generates a
function call to the replacement function.

The problems observed by Andi only occur in recent kernels without
-fno-unit-at-a-time.

With -ffreestanding it can't even cause any problems in case we'd one day drop
the -fno-unit-at-a-time since gcc mustn't assume in a freestanding environment
that all standard C library functions are available.

The effect of this patch is a small space saving in the kernel.
