 vpid_sync_vcpu_addr()

Sean Christopherson <sean.j.christopherson@...el.com> writes:
>Directly invoke vpid_sync_context() to do a global INVVPID when the individual address variant is not supported instead of deferring such behavior to the caller.  This allows for additional consolidation of code as the logic is basically identical to the emulation of the individual address variant in handle_invvpid().
