due to:

(same error for all of them, the warning appears non-fatally in
other configs).  This is caused by f13d13caa6ef2 (mm/sparse.c:
fix memory leak of sparsemap_buf in aliged memory) which adds a
reference from the __meminit annotated sparse_buffer_alloc() to
the newly added __init annotated sparse_buffer_free().
