https://en.wikipedia.org/wiki/Alder_Lake CPUs have multiple cores where some of them (performance cores) have CPU_HT

src/hotspot/cpu/x86/vm_version_x86.hpp
    decl(HT, "ht", 3) \

set while other cores (efficient cores) have CPU_HT unset.

src/hotspot/cpu/x86/vm_version_x86.cpp initialization can run randomly on any of the cores. This may set UseUnalignedLoadStores, AllocatePrefetchLines and AllocatePrefetchDistance suboptimally for the whole remaining run of OpenJDK.

It is sure questionable whether CPU_HT should be set or unset on these hybrid CPUs. I guess it should be set as the performance matters on the performance CPUs.
