commit: 6ddc990b96df159a95b1f6c50f207c20b409f818 [276/278] KVM: SVM: Move Nested SVM Implementation to nested.c
config: i386-allyesconfig (attached as .config)
compiler: gcc-7 (Debian 7.5.0-5) 7.5.0
reproduce:
        git checkout 6ddc990b96df159a95b1f6c50f207c20b409f818
        # save the attached .config to linux build tree
        make ARCH=i386
