Argh. This is all depending on a special gcc option to compile the kernel and that option limits the kernel to the upper 2GB. So I guess for CPU_PTR we need to explicitly load the address as a constant, use that as a base and then add the offset and the smp_id shifted to it in the instruction. The CPU_INC/DEC stuff using gs is not affected. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
