I don't know what tree you've done those patches against but against -rc6+, the
first argument above needs to be vcpu->kvm:
arch/x86/kvm/x86.c: In function ‘kvm_arch_vcpu_ioctl’:
arch/x86/kvm/x86.c:4343:41: error: ‘kvm’ undeclared (first use in this function)
r = kvm_x86_ops->get_page_enc_bitmap(kvm, &bitmap);
^~~
arch/x86/kvm/x86.c:4343:41: note: each undeclared identifier is reported only once for each function it appears in
make[2]: *** [scripts/Makefile.build:280: arch/x86/kvm/x86.o] Error 1
