Well, we don't have any per-CPU data unless we're building for SMP. See: #ifndef PER_CPU_BASE_SECTION #ifdef CONFIG_SMP #define PER_CPU_BASE_SECTION ".data..percpu" #else #define PER_CPU_BASE_SECTION ".data" #endif #endif in include/asm-generic/percpu.h. -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
