Impact: new API Add a helper function that takes two cpumask's, and's them and then returns the apicid of the result. This removes a need in io_apic.c that uses a temporary cpumask to hold (mask & cfg->domain). Signed-off-by: Mike Travis <travis@sgi.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
