SubjectRe: [PATCH v6 7/7] KVM: x86: Allow Qemu/KVM to use PVH entry point
Hi Maran,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on linus/master]
[also build test WARNING on next-20180405]
[cannot apply to tip/x86/core xen-tip/linux-next v4.16]
[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/Maran-Wilson/KVM-x86-Allow-Qemu-KVM-to-use-PVH-entry-point/20180405-165048
config: i386-allmodconfig (attached as .config)
compiler: gcc-7 (Debian 7.3.0-1) 7.3.0
reproduce:
# save the attached .config to linux build tree
make ARCH=i386
