Interesting. Since the feature in question is billed first of all a
performance optimization...
By whom? Although I see some improved performance, I think its real
benefit is improving memory utilization on the guest. Instead of using
75K for an ARP packet, mergeable RX buffers only uses 4K.
This is necessary to implement Nested Nested Paging. As a
side effect this allows some cleanups in the SVM nested
paging code.

This capability shows userspace that is can trust the values

This patch adds code to ask the kernel about the svm
features it supports for its guests and propagates them to
the guest. The new capability is necessary because the old
behavior of the kernel was to just return the host svm
features but every svm-feature needs emulation in the nested
svm kernel
This patch fixes the propagation of the ext3_features from
the qemu cpu-model to kvm. This is required for the guest to
see the svm flag.
