mm/page_alloc.o has size changes:
Without this patch:
$ size mm/page_alloc.o
text data bss dec hex filename
36695 9792 8396 54883 d663 mm/page_alloc.o
With this patch:
$ size mm/page_alloc.o
text data bss dec hex filename
37511 9792 8396 55699 d993 mm/page_alloc.o
But vmlinux doesn't.
It's not clear to me what happened, do you want to me dig this out?
