Since the original code is this:

switch(clustered_apic_mode){
case CLUSTERED_APIC_NUMAQ:
/* Broadcast intrs to local quad only. */
return APIC_BROADCAST_ID_APIC;
case CLUSTERED_APIC_XAPIC:
/*round robin the interrupts*/
cpu = (cpu+1)%smp_num_cpus;
return cpu_to_physical_apicid(cpu);
default:
}
return cpu_online_map;

my patch doesn't change anything. It may be a bit unclean though. What
about this one:

diff -Nru -X dontdiff linux-2.4-vanilla/include/asm-i386/smpboot.h linux-2.4/include/asm-i386/smpboot.h
