default IRQ affinity change in v2.6.27 (breaking several SMP PPC based systems)

It appears the default IRQ affinity changes from being just cpu 0 to
all cpu's. This breaks several PPC SMP systems in which only a single
processor is allowed to be selected as the destination of the IRQ.
What is the right answer in fixing this? Should we:
cpumask_t irq_default_affinity = 1;
cpumask_t irq_default_affinity = CPU_MASK_ALL?
