You'll also need to retrigger the 'do_relaunch' path in 
arch_vmx_do_resume after a sync. Could do that by setting launch_cpu to 
-1 after sync'ing.
That'll take you down the else path in arch_vmx_do_resume, and all you 
need to do is have vmx_request_clear_vmcs() detect and ignore 
launch_cpu==-1.
