This is overly abstracted. It's not like you can (on real hardware)
wire your own lapic and plug it into the processor. It's well defined,
and there are just three modes of operation:
- emulated by userspace
- emulated in-kernel, but disabled
- emulated in-kernel
The differentiation can be made by installing or not installing the mmio
handler and the irqdevice stuff.
