So we have a second use case for CPU-local I/O regions? I wonder if only a single CPU can enter SMM or if all have to.For the i440fx, it's a chipset register (not a per-CPU register). Maybe it's per-CPU on more modern chipsets... I'm not really sure.
IIRC the chipset register is only used during setup, so you can have access to this memory without entering SMM mode. Once you are in SMM mode, you don't need to touch anything.
