First off, apologies for sitting on this for so long.
I just made a first-pass attempt at merging this. Most of
(maybe all?) the simpler bits are in (whitespace changes, typos etc).
I'll push that out to bkbits soon, so the powernow-k8 diff in the
next -mm that Andrew builds should be slightly smaller at least.

The ACPI stuff I'm pondering.
Bruno, how does this stuff look to you? Your acpi perflib stuff is
already in the pending pool (see the diff in the current -mm tree at
http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.5-rc3/2.6.5-rc3-mm4/broken-out/bk-cpufreq.patch)
Would this driver be better off using that ?

This bit just looks *wrong* to me.  This looks like something
that really should be sorted out in Kconfig.

The rest of the ACPI changes, I'd really like to get Bruno Ducrot's opinion
on.
