Krish Sadhukhan - Feb. 7, 2019, 7:05 p.m.
The error code returned by KVM when vmlaunch fails, is hard-coded in
'test_vmx_controls'. Because that function has been thus far used only for
testing the VMX controls. Re-name the function to 'test_vmx_vmlaunch' and pass
the expected error code to it so that it can be used for testing any VMCS
field.
Add two wrappers around 'test_vmx_vmlaunch' for testing the VMX controls.
