Hi, Jes
Yes, Anthony and I are working with kernel-ia64 and kvm community to
push the patches. Since kernel should export some interface for kvm
use, we have to wait the response from kernel-ia64. But anyway, It
should be picked up in near future.

The mapping function for the nonpaging case in the softmmu does basically the
same as required for Nested Paging. Make this function generic so it can be
used for both.

The generic x86 code has to know if the specific implementation uses Nested
Paging. In the generic code Nested Paging is called Hardware Assisted Paging
(HAP) to avoid confusion with (future) HAP implementations of other vendors.
This patch exports the availability of HAP to the generic x86 code.
Let SVM detect if the Nested Paging feature is available on the hardware.
Disable it to keep this patch series bisectable.

By moving the SVM feature detection from the each_cpu code to the hardware
setup code it runs only once. As an additional advance the feature check is now
available earlier in the module setup process.
