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

>> WARNING: modpost: vmlinux.o(.text+0x566a2): Section mismatch in reference from the function arch_alloc_nodedata() to the function .init.text:memblock_alloc_try_nid()
The function arch_alloc_nodedata() references
the function __init memblock_alloc_try_nid().
This is often because arch_alloc_nodedata lacks a __init
annotation or the annotation of memblock_alloc_try_nid is wrong.
