Why? It looks like it should be slower because of an extra redirection on the page table. However, since 586 doesn't include cmov it may not be slower than 586. The other benefit it appears to provide is being able to mark pages as not executable. I don't know whether or not that actually buys anything when using Fedora. -- fedora-test-list mailing list fedora-test-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-test-list
