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?
