How does userspace know they exist?

#ifdef KVM_INTERRUPT_SET? MOL is the only user of this so far. And that
won't work without the hypervisor call anyways.

We generally compile on one machine, and run on another.
So? Then IRQ unsetting doesn't work. Without this series you won't get
much further than booting the kernel anyways because XER is broken, TLB
flushes are broken and FPU loading is broken. So not being able to unset
an IRQ line is the least of your problems :).

There's a difference between an error message telling you to upgrade to a kernel with KVM_CAP_BLAH and a failure. It's the difference between a bug report and silence.
