Well, I think right now one issue is that you can't avoid it, even
when you want pure "raw hardware" spinlocks.
I really think it should at the very least be inside CONFIG_PARAVIRT.
Because it *is* about helping the hypervisor, so really is about
paravirtualization.
So naming is misleading, I think, and the config option situation is
not great. If you act differently under virtualization than you do on
raw hardware, what would you call that? I'd call it "paravirt".
