Date: Wed, 4 Nov 2009 21:20:40 +0800 From: Yong Zhang <yong.zhang0@...il.com> To: linux-kernel@...r.kernel.org Cc: Ingo Molnar <mingo@...e.hu>, Thomas Gleixner <tglx@...utronix.de> Subject: [PATCH 2/3] genirq: set irq thread affinity when doing __setup_irq setup_affinity() should be paired with irq_set_thread_affinity() even in the setup stage of an irq. Because irq_default_affinity could be initialized by arch code in which case affinity between irq and thead will be inconsistent.
