Hi Simon, Thank you for the patch! Yet something to improve: [auto build test ERROR on powerpc/next] [also build test ERROR on v4.17-rc2 next-20180426] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system] url: https://github.com/0day-ci/linux/commits/wei-guo-simon-gmail-com/KVM-PPC-add-pt_regs-into-kvm_vcpu_arch-and-move-vcpu-arch-gpr-into-it/20180427-055410 base: https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git next config: powerpc-defconfig (attached as .config) compiler: powerpc64-linux-gnu-gcc (Debian 7.2.0-11) 7.2.0 reproduce: wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross chmod +x ~/bin/make.cross # save the attached .config to linux build tree make.cross ARCH=powerpc Note: the linux-review/wei-guo-simon-gmail-com/KVM-PPC-add-pt_regs-into-kvm_vcpu_arch-and-move-vcpu-arch-gpr-into-it/20180427-055410 HEAD 92a7de2f1920f80f57d625d6d07731a00ea99161 builds fine.
