[PATCH v2 0/3] cpufreq: intel_pstate: Adjust the energy model for hybrid systems

Hi Everyone,
This supersedes
https://lore.kernel.org/linux-pm/5937608.DvuYhMxLoT@rafael.j.wysocki/
because the last patch in it resulted from some confusion. Sorry about that.
In this series patch [3/3] simply switches over the energy model callbacks to
using CPU types retrieved from CPUID instead of scaling factors which is more
robust and allows the energy model to be tuned more precisely. In particular,
it will now allow P-cores to be populated when E-cores are utilized above 60%
of their capacity (and not just in the "overutilized" situation or when there
is a task whose utilization exceeds the E-core capacity).
The first two patches in the series are preliminary.
Thanks!
