Only call kvm_set_irqfd() if CONFIG_KVM is defined to avoid breaking
the build for non x86.
You can just add a stub to kvm-stub.c that returns -ENOSYS.

It's more than that, the code also uses bits in the msix code that isn't
globally available.
I see now. BTW, my eventnotifier series conflicts with this part of
qemu-kvm, so it's probably better if I work that series out in qemu-kvm
first and then upstream. As I would touch this code anyway, I think
your patch is fine even if it were be only a stopgap measure.
Maybe the right fix, which I could include in my series, is to change
kvm_set_irqfd's calling convention to be like this:
int r = kvm_set_irqfd(&dev->msix_irq_entries[vector],
event_notifier_get_fd(notifier),
!masked);
and extract the gsi in the function. Michael, does this make any sense?
