Though looking at system_event, isn't that missing padding after type? Ah, KVM
doesn't actually populate flags, wonderful. Maybe we can get away with tweaking
it to:
struct {
__u32 type;
__u32 ndata;
__u64 data[16];
} system_event;
Yes, you can do that and say that the ndata is only valid e.g. if bit 31
is set in type.
I agree with reusing KVM_EXIT_SYSTEM_EVENT, that would be a much smaller
patch. Sorry about that Peter.
