64-bit uses MSRs for important things like the base for fs and gs-prefixed addresses. It's more efficient to use a hypercall to update these, rather than go via the trap and emulate path. Other MSR writes are just passed through; in an unprivileged domain they do nothing, but it might be useful later.
