I thought about this field for a while. What we really want, is that 
the common code can figure wheter or not it is a good idea to send an 
interrupt. All architectures (even including s390) could encode an 
interrupt number in a 64bit value. To me, it looks like a callback for 
this like
int kvm_arch_interrupt_window_open(u64 interrupt);
would be the right abstraction. No need to solve this whole thing with 
this patch though, that aims at splitting kvm_vcpu.

so long,
Carsten
