I hope it is OK to ask a newbie question here. 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
