003f230e37 ("machine: Tweak the order of topology members in struct
CpuTopology") changes the meaning of MachineState.smp.cores from "the
number of cores in one package" to "the number of cores in one die"
and doesn't fix other uses of MachineState.smp.cores. And because of
the introduction of cluster, now smp.cores just means "the number of
cores in one cluster". This clearly does not fit the semantics here.
And before this error message, WHvSetPartitionProperty() is called to
set prop.ProcessorCount.
So the error message should show the prop.ProcessorCount other than
"cores per cluster" or "cores per package".

The mingw64-headers package included in the Fedora version we

Use the renamed header in order to detect and successfully
