I'm trying to better understand the boot process. I can't seem to find where in the kernel sources the cpu_active_mask (defined in include/linux/cpumask.h) gets populated. I can see that it does get populated as it brings cpus online but it is not obvious to me where. I'm using a 32 bit 3.4.x flavor kernel. Sorry for the noise and thanks for any pointers Regards Mark
