From 7eb9ae0799b1e9f0b77733b432bc5f6f055b020b Mon Sep 17 00:00:00 2001 From: Suresh Siddha Date: Thu, 14 Jun 2012 18:28:49 -0700 Subject: irq/apic: Use config_enabled(CONFIG_SMP) checks to clean up irq_set_affinity() for UP Move the ->irq_set_affinity() routines out of the #ifdef CONFIG_SMP sections and use config_enabled(CONFIG_SMP) checks inside those routines. Thus making those routines simple null stubs for !CONFIG_SMP and retaining those routines with no additional runtime overhead for CONFIG_SMP kernels. Cleans up the ifdef CONFIG_SMP in and around routines related to irq_set_affinity in io_apic and irq_remapping subsystems.
