Aaron Lewis 9753d68865 KVM: VMX: Use wrmsr for switching between guest and host IA32_XSS on Intel
When the guest can execute the XSAVES/XRSTORS instructions, use wrmsr to
set the hardware IA32_XSS MSR to guest/host values on VM-entry/VM-exit,
rather than the MSR-load areas. By using the same approach as AMD, we
will be able to use a common implementation for both (in the next
patch).
