All warnings (new ones prefixed by >>, old ones prefixed by <<):

>> WARNING: modpost: vmlinux.o(.text+0x2840fa): Section mismatch in reference from the function atomic_pool_expand() to the function .meminit.text:memblock_start_of_DRAM()
The function atomic_pool_expand() references
the function __meminit memblock_start_of_DRAM().
This is often because atomic_pool_expand lacks a __meminit
annotation or the annotation of memblock_start_of_DRAM is wrong.
