Are you referring to cleanup of ACPI P-state driver by Dominik? That patch is indeed nice and clean. But that is mostly orthogonal to this patch. I mean, - SMP awareness in P-state driver - P-state coordination between HT siblings will still be required even after Dominik's patch. Though exact location of these changes will change when applied over Dominik's patch.
There is a small overlap in handling MSR based P-state transitions, but that is a real minor change in my patch and I am reusing most of the existing IO based transitions code for MSR based ones.

I am sorry. I do not understand this comment. - Major part of Patch 1 is adding SMP awareness, which has nothing specific to Intel at all. - A part of patch 1 adds MSR based transition capability. This is based on ACPI spec. It will work any processor that is ACPI compatible and again there are no specific checks for Intel here.
