Stop compiling vmenter.S with OBJECT_FILES_NON_STANDARD to skip objtool's stack validation now that __svm_vcpu_run() and __svm_sev_es_vcpu_run() create stack frames (though the former's effectiveness is dubious). Note, due to a quirk in how OBJECT_FILES_NON_STANDARD was handled by the build system prior to commitbf48d9b756("kbuild: change tool coverage variables to take the path relative to $(obj)"), vmx/vmenter.S got lumped in with svm/vmenter.S. __vmx_vcpu_run() already plays nice with frame pointers, i.e. it was collateral damage when commit7f4b5cde24("kvm: Disable objtool frame pointer checking for vmenter.S") added the OBJECT_FILES_NON_STANDARD hack-a-fix.
