I just noticed this on sparc64, as I lost 31 cpus on my Niagara box due to it :)
boot_cpu_init() sets the boot processor ID in cpu_present_map.
But fixup_cpu_present_map() will only populate the cpu_present_map if it is empty, which it won't be because of what boot_cpu_init() just did. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
