This looks like a worth-while thing to do. Do you have any performance measurements to justify the change? This will increase the size of struct kvmppc_ics by 4kB, so it would be useful to show the performance increase that justifies it. Also, when you resend the patch, please make the patch description more definite - say "With this patch, we use" rather than "this patch tries to use", for instance.
