Specifically, ia64 is limited to 64k in percpu vars and with NR_CPUS=4096, that ends up being 32k by itself. It ends up causing link errors since that is how ia64 enforces the 64k limit. I can take a deeper look at finding a workable solution but thought I'd mention it in case you had ideas already. -Jeff -- Jeff Mahoney SuSE Labs -- 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/
