From 7a0d7940e7c7c143520e38900ddd4e217d3c6640 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Tue, 2 Dec 2008 13:37:01 -0600 Subject: powerpc: Use physical cpu id when setting the processor affinity 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.
