As reported a few times[1][2], these two collided and cause a build failure when
building with CONFIG_KVM_AMD=m.
ERROR: modpost: "kvm_hv_assist_page_enabled" [arch/x86/kvm/kvm-amd.ko] undefined!
make[2]: *** [scripts/Makefile.modpost:126: Module.symvers] Error 1
make[1]: *** [Makefile:1944: modpost] Error 2
