Message-Id: <1228246621-25622-1-git-send-email-galak@kernel.crashing.org> Date: Tue, 2 Dec 2008 13:37:01 -0600 From: Kumar Gala <galak@...nel.crashing.org> To: Paul Mackerras <paulus@...ba.org> Cc: linuxppc-dev@...abs.org, linux-kernel@...r.kernel.org, Linus Torvalds <torvalds@...l.org>, Andrew Morton <akpm@...l.org> Subject: [PATCH][for 2.6.28] 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.
