McKenney" , Lai Jiangshan , Bharata B Rao , Lee Schermerhorn , Rik van Riel , Johannes Weiner , Srivatsa Vaddagiri , Christoph Lameter Add the config options to allow building the kernel with AutoNUMA. If CONFIG_AUTONUMA_DEFAULT_ENABLED is "=y", then /sys/kernel/mm/autonuma/enabled will be equal to 1, and AutoNUMA will be enabled automatically at boot. CONFIG_AUTONUMA currently depends on X86, because no other arch implements the pte/pmd_numa yet and selecting =y would result in a failed build, but this shall be relaxed in the future. Porting AutoNUMA to other archs should be pretty simple.
