Hi Coleen,
The code relocation seems okay. Good cleanup!
One query below on `CPUInformationInterface::initialize()`.
Good catch on the `Abstract_VM_Version` calls in jvm.cpp! I missed that in the
review of JDK-8241071.
Thanks,
David

I can't figure out when this code will actually get executed in relation to
the VM initialization process and VM_Version's initialization. Can this
actually execute before that happens? Or could we assert that it has happened?
