Patches 1-3 address bugs in the current frequency invariance support for x86, including the incompatibility with cpu0 hotplug reported by Chris Wilson at https://lore.kernel.org/lkml/158556634294.3228.4889951961483021094@build.alporthouse.com/ and the issue with CPUs that have less than 4 cores pointed out earlier today by Like Xu at https://lore.kernel.org/lkml/20200416021210.170736-1-like.xu@linux.intel.com/
Patch 4 is a minor code reorganization.
Giovanni Gherdovich (3): x86, sched: Bail out of frequency invariance if base frequency is unknown x86, sched: Account for CPUs with less than 4 cores in freq. invariance x86, sched: Move check for CPU type to caller function
Peter Zijlstra (Intel) (1): x86, sched: Don't enable static key when starting secondary CPUs
