Better to set this up as an MSR (with bit zero enabling, bits 1-5
features, and 64-byte alignment). This allows auto-reset on INIT and

Yes. Once a kernel is released you can't realistically change the version.
Some documentation for this?
Also, the

Why not? If version doesn't match apf will not be used.
