Yonghua Huang 4fc5dcfc3e hv: enable SMAP in hypervisor 
With SMAP enabled, hypervisor can't access pages that
owned by guest(either SOS or UOS), and an override is
is provided: stac()/clac() to enable/disable access to
guest's memory pages.

 Pre-conditon:
    Mark hypervisor owned pages as supervisor mode (U/S = 0),
       and set all othter memory pages as user mode (U/S = 1).
