Hi Everyone,

The first patch in this series modifies intel_pstate to use nformation from
CPPC for computing perf-to-frequency scaling factors on hybrid systems as
per the subject.

The second patch removes Arrow Lake from the list of platforms for which
the scaling factor is known because in fact the Meteor Lake scaling factor
will not be suitable for it in all configurations.

These patches have been sent already which the following RFC series:

https://lore.kernel.org/linux-pm/5861970.DvuYhMxLoT@rjwysocki.net/

but as stated there, they are really 6.14 material independent of the
other patches in it.

Thanks!
