Feng Wu e1e746b3c5 KVM: Disable SMAP for guests in EPT realmode and EPT unpaging mode ...

SMAP is disabled if CPU is in non-paging mode in hardware.
However KVM always uses paging mode to emulate guest non-paging
mode with TDP. To emulate this behavior, SMAP needs to be
manually disabled when guest switches to non-paging mode.
