| |
We plan to remove cpu_possible_map and cpu_present_map later and we have proper init_cpu_possible() and init_cpu_present() APIs.
Therefore this patch rewrites platform_init_cpus and platform_prepare_cpus by their APIs.

I sent this parch to wrong address (device-driver-devel@blackfin.uclinux.org). thus now I'm resending it.
