Yeey! One question - I know you had questions about the PROT_GLOBAL | ~PAGE_PRESENT being set on PTEs that are going to be harvested for AutoNUMA balancing. And that the hypercall to set such PTE entry disallows the PROT_GLOBAL (it stripts it off)? That means that when the Linux page system kicks in (as it has ~PAGE_PRESENT) the Linux pagehandler won't see the PROT_GLOBAL (as it has been filtered out). Which means that the AutoNUMA code won't kick in. (see http://article.gmane.org/gmane.comp.emulators.xen.devel/174317) Was that problem ever answered? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
