Think about virtualization technologies such as VMware, Xen and KVM. If those can implement an alternate page table update mechanism then we do not need many of the hooks that are currently being proposed. There is the potential that we can come up with forms of page tables that avoid the current issues with shadow page tables. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
