This patch was worked on 4.2(inherited to 4.4) to have correct numa_node populated on sysfs. however, on 4.4, OF is fixed to set numa_node(fixed by 56f2de81e020c537f7e35550d13840143cb765cd) This patch (patch #5) is not required and will be dropped. thanks for your comments. > > Lorenzo thanks Ganapat -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
