Hi Michal,

[auto build test WARNING on mmotm/master]
[also build test WARNING on v4.12-rc3 next-20170530]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url:    https://github.com/0day-ci/linux/commits/Michal-Hocko/mm-consider-memblock-reservations-for-deferred-memory-initialization-sizing/20170531-153111
base:   git://git.cmpxchg.org/linux-mmotm.git master
config: x86_64-acpi-redef (attached as .config)
compiler: gcc-6 (Debian 6.2.0-3) 6.2.0 20160901
reproduce:
        # save the attached .config to linux build tree
        make ARCH=x86_64 

All warnings (new ones prefixed by >>):

>> WARNING: mm/built-in.o(.text+0x3cbaa): Section mismatch in reference from the function memblock_reserved_memory_within() to the variable .meminit.data:memblock
   The function memblock_reserved_memory_within() references
   the variable __meminitdata memblock.
   This is often because memblock_reserved_memory_within lacks a __meminitdata
   annotation or the annotation of memblock is wrong.
