Mark Langsdorf points out that the correct define for this
revision bump is 0x80000. Also to save us having to keep
renaming the #define, give it a more meaningful name.

fill_powernow_table_pstate() and fill_powernow_table_fidvid() are only
defined and used for X86_POWERNOW_K8_ACPI.

The fid/vid masks for parts using the extended parts are slightly incorrect and can result in
incorrect fid/vid codes being applied. No instances of this problem have been reported in
the field but it could be a problem with future parts.

Forthcoming AMD products will use a different algorithm for transitioning
pstates than the current generation Opteron products do. The attached
patch allows the powernow-k8 driver to work with those products.

Future versions of the Opteron processor may support
frequency transitions of 100 MHz, instead of the=20
current 200 MHz. This patch enables the powernow-k8
driver to transition to an odd FID code, indicating
a multiple of 100 MHz frequency.

can be encoded in the current driver's 4 bit frequency
field. This patch updates the driver to support Rev F
including 6 bit FIDs and processor ID updates.
This should apply cleanly whether or not the dual-core
bugfix I sent out last week is applied. I'd prefer
that both get applied, of course.

With the release of the dual-core AMD Opterons last week,
it's high time that cpufreq supported them. The attached
patch applies cleanly to 2.6.12-rc3 and updates powernow-k8
to support the latest Athlon 64 and Opteron processors.
Update the driver to version 1.40.0 and provide support
for dual-core processors.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
