I use allmodconfig, but that doesn't really build at the moment, so I
have attached a config that should build (with a recent Linus tree).

WARNING: mm/built-in.o - Section mismatch: reference to .init.text:.__alloc_bootmem_node from .text between '.sparse_index_alloc' (at offset 0x27df0) and '.__section_nr'

The '.sparse_index_alloc' doesn't match "sparse_index_alloc" in pat4sym
due to the '.' at the beginning.  I have seen another one as well, but
cannot reproduce it at the moment.
