SubjectRe: [PATCH v2 12/15] KVM: Provide common implementation for generic dirty log functions
Hi Sean,

I love your patch! Yet something to improve:

[auto build test ERROR on kvm/linux-next]
[cannot apply to v5.4-rc4 next-20191024]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]

url: https://github.com/0day-ci/linux/commits/Sean-Christopherson/KVM-Dynamically-size-memslot-arrays/20191024-144336
base: https://git.kernel.org/pub/scm/virt/kvm/kvm.git linux-next
config: mips-malta_kvm_defconfig (attached as .config)
compiler: mipsel-linux-gcc (GCC) 7.4.0
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
GCC_VERSION=7.4.0 make.cross ARCH=mips

If you fix the issue, kindly add following tag
