[PATCH][for 2.6.28] powerpc: Use physical cpu id when setting the processor affinity

From: Kumar Gala
Date: Tue Dec 02 2008 - 14:37:55 EST

In the CONFIG_SMP case the irq_choose_cpu() code was returning back
a logical cpu id not the physical id. We were writing that directly
into the HW register.

We need to be calling get_hard_smp_processor_id() so irq_choose_cpu()
always returns a physical cpu id.
