so we can merge io_apic_32.c and io_apic_64.c v2: Use cpu_online_map as target cpus for bigsmp, just like 64-bit is doing. Also remove some unused TARGET_CPUS macro. v3: need to check if desc is null in smp_irq_move_cleanup also migration needs to reset vector too, so copy __target_IO_APIC_irq from 64bit. (the duplication will go away once the two files are unified.) Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
