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

>> WARNING: modpost: vmlinux.o(.text+0x8cc4): Section mismatch in reference from the function __arm_ioremap_pfn_caller() to the function .meminit.text:memblock_is_map_memory()
The function __arm_ioremap_pfn_caller() references
the function __meminit memblock_is_map_memory().
This is often because __arm_ioremap_pfn_caller lacks a __meminit
annotation or the annotation of memblock_is_map_memory is wrong.
