From: Kevin Winchester on 5 Jul 2010 19:10 In the CONFIG_INTR_REMAP=N case, most dmar functions become one- line static inline functions. However a few functions were instead defined to constants. This causes the following warnings for me: arch/x86/kernel/apic/apic.c: In function 'lapic_suspend': arch/x86/kernel/apic/apic.c:2014:3: warning: statement with no effect arch/x86/kernel/apic/apic.c: In function 'lapic_resume': arch/x86/kernel/apic/apic.c:2091:3: warning: statement with no effect Correct these warnings by converting the defines into static inline functions instead.
