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.
