base: git://git.cmpxchg.org/linux-mmotm.git master

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.
