This patch fails the build because of vmx_has_valid_vmcs12() in nested.h which uses EVMPTR_INVALID.

vmx/nested.h includes vmx/vmx.h which includes vmx_ops.h, it includes vmx_onhyperv.h which used to include hyperv.h but not anymore.

We can either add hyperv.h to vmx/nested.h, or we can move the code in vmx_has_valid_vmcs12 to hyperv_evmcs.h.

Besides the build error,
