KVM: VMX: enable VMXON check with SMX enabled (Intel TXT)
Per document, for feature control MSR:
Bit 1 enables VMXON in SMX operation. If the bit is clear, execution
of VMXON in SMX operation causes a general-protection exception.
Bit 2 enables VMXON outside SMX operation. If the bit is clear, execution
of VMXON outside SMX operation causes a general-protection exception.
This patch is to enable this kind of check with SMX for VMXON in KVM.
