2.5.x IRQ changes for PT Digital Board.
Also some code cleanups.

Changed files:
linux/arch/arm/mach-sa1100/system3.c
linux/include/asm-arm/arch-sa1100/irqs.h
linux/include/asm-arm/arch-sa1100/system3.h

This renames Cotulla to its official name.

Updated the IRQ code to the new model.
also removed some dead code.

Not tested (the tree is too broken to compile) but this should still 
be better than totally wrong and obsolete code.

loops within loops within loops checking until each IRQ level didn't
have any more interrupts for us.  This caused both latency problems,
and locked out any chance of handling a second interrupt from down
the chain while one on that chain was already in progress.

The new structure splits out the machine specific IRQ handlers from
the Linux driver specific IRQ handlers, giving the machine specific
handlers much greater flexibility in handling the interrupt.  We
also suck the SA1100 IRQ edge selection function into the IRQ core.

Patch 960/1 (Peter Teichmann):
   NWFPE patch to be more compliant to IEEE-754

1. The RND/URD instruction was handled as int_to_float(float_to_int
   (number)) which is wrong because it only works for floating point
   numbers that fit in an integer.

2. The FLT instruction was setting the rounding precision for
   extended precision calculations, which is not necessary
   (probably a historic relict) but has undesirable side effects
   on all extended precision calculations.

replication across each processor type, each handling alignment of
addresses slightly differently.  We unify this mess, and allow for
greater flexibility in the per-CPU architecture TLB handlers.

We also start to remove the ARM cache.h -> cpu_*.h -> proc-fns.h mess
making the code cleaner and easier to follow.

Documentation describing the expected behaviour of each TLB function
for the 32-bit ARM processors is also included.

the lvm-patch that went into 2.5.5 missed the changes in lvm.h and is
still not compileable. This patch adds those changes. The kernel i'm
running right now has this patch and /var and /home on lvm.

A forward-port of all the .text.exit fixes which went into
2.4.   Also contains a couple of s/MINOR/minor/ changes.

Al updated Documentation/filesystems/porting with 2.5 changes but there
is no mention of lseek.  The following patch, against 2.5.5, adds lseek
to the list of functions that no longer are called with the BKL.

The attached patch implements proper locking in ALSA lseek methods.
Note ALSA has 3 lseek implementations, but only:

	sound/core/info.c :: snd_info_entry_llseek()

requires locking.  I wrapped the function in the BKL.  According to
Jaroslav Kysela the gus_mem_proc method is only called from above.  The
third lseek, in hwdep.c, clearly doesn't need locking.  Without this
patch, the above lseek is not safe.

	Robert Love

This patch add the validity check of 2 values (fats, reserved). These
values must not be 0.

Here enclosed patch for eata.c, eata.h, u14-34f.c, u14-34f.h
to be applied to lk-2.5.5.

eata.c:
       + Remove any reference to virt_to_bus().
       + Fix pio hang while detecting multiple HBAs.
       + Fixed a board detection bug: in a system with
         multiple ISA/EISA boards, all but the first one
          were erroneously detected as PCI.

u14-34f.c:
       + Remove any reference to virt_to_bus().
       + Fix pio hang while detecting multiple HBAs.

After BKL was moved from the VFS into the filesystem's methods in the lookup
call, we do not need to check BKL is actually held (we know it is not).
This patch patch removes unneeded lock_depth check.
Without this patch reiserfs cannot be used on SMP.

2.5.5 Oopses at boot time with a disk in a zipdrive.
With this patch all is fine. I have not read the
patch, certainly not checked it for correctness,
just observed that it works for me.
I think the author is Rich Baum.
