Hi Xishi, FYI, there are new compile warnings show up in commit: ca57df79d4f64e1a4886606af4289d40636189c5 mm: setup pageblock_order before it's used by sparsemem config: powerpc-allyesconfig # make ARCH=powerpc allyesconfig All warnings: WARNING: vmlinux.o(.meminit.text+0x1228): Section mismatch in reference from the function .free_area_init_core.isra.34() to the function .init.text:.set_pageblock_order() The function __meminit .free_area_init_core.isra.34() references a function __init .set_pageblock_order(). If .set_pageblock_order is only used by .free_area_init_core.isra.34 then annotate .set_pageblock_order with a matching annotation. --- 0-DAY kernel build testing backend Open Source Technology Center Fengguang Wu, Yuanhan Liu Intel Corporation -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
