In your config above, CONFIG_DMA_CMA is not even set, so the contigous.c should not be compiled. Could you help to double check? thanks! - Feng > Kconfig warnings: (for reference only) > WARNING: unmet direct dependencies detected for HOTPLUG_CPU > Depends on [n]: SMP [=y] && (PPC_PSERIES [=n] || PPC_PMAC [=n] || > PPC_POWERNV [=n] || FSL_SOC_BOOKE [=n]) > Selected by [y]: > - PM_SLEEP_SMP [=y] && SMP [=y] && (ARCH_SUSPEND_POSSIBLE [=y] || > ARCH_HIBERNATION_POSSIBLE [=y]) && PM_SLEEP [=y] > > -- > 0-DAY CI Kernel Test Service > https://github.com/intel/lkp-tests/wiki
