changes and fix a race with the PMU driver

that could prevent one of the timeouts from working, fix access
to MMIO based interface

support for Kauai ATA/100 and add activity led code.
NOTE: The activity LED code has been left out of Kconfig until the
proper support for it in the blk & ide layers have been merged
(pending patch from Jens Axboe) 

 - Adapt to new power management
 - Make PM and cpufreq more robust by preventing ADB requests
   from getting in after the actual freq change / sleep one
 - Close a few races
 - Expose some IRQ stats & fix a problem where core99 machines
   were getting tons of spurrious ADB events

it more robust vs. concurrent calls by the PM system and cpufreq

model changes. Fix refcounting

  Fix CPU table, 750FX rev 1.x must not tab high BATs

On PPC32 we reorder the arguments so they fit into 6 registers.  Glibc will
need a two-line stub to change them from the standard order to the ordering
used by the system call: (fd, advice, offset, len).

In both 2.4 and in 2.6, error handling for bad cdrom media is
wrong.  And it is my fault I'm afraid, since I botched an earlier
fix for the problem by putting the fix in the wrong spot.

My kids have a "Jumpstart Toddlers" cd they have long since
completely killed, which makes a great test disc.  Without this
fix, the best time projection I can get for completing a dd type
sector copy is about 2 years...  Most of that is spent thrashing
about in kernel space trying to re-read sectors we already know
are not correctable....  After the fix, I was able to rip a copy
the CD (or rather muddle through it getting lots of EIO errors)
in about 15 minutes.

Attached is the fix for 2.6.x,

From David Mosberger:

Yes, looks good: reset the iterator at allocation.

Remove the PCMCIA release timer that got missed in earlier patch.  This
is required for successful compilation of the driver.

Cleanup of nfs_lookup() by me...

o machine depend header cleanup
o interrupt management fix
