Can we please get a few MIPS defconfigs added to the 0-day testing? - malta_kvm_defconfig this probably doesn't need to be a high priority build, but other configs don't yet cover MIPS KVM so its worth having (that bit us recently with 3.12 and 4.4 stable branches). - 64r6el_defconfig and 32r2_defconfig (4.9 and later) these are just a couple of the new generic/multiplatform kernel configurations added in 4.9 (Paul Burton Cc'd). There are others too, but these will probably give decent coverage. These are likely to be increasingly relevant as more/new platforms are converted to use it. (note, the r6 one may require a newish toolchain).
