Calling an __init function from a __meminit function is not allowed:
WARNING: vmlinux.o(.meminit.text+0x30ff): Section mismatch in reference from the function sparse_buffer_alloc() to the function .init.text:sparse_buffer_free()
The function __meminit sparse_buffer_alloc() references
a function __init sparse_buffer_free().
If sparse_buffer_free is only used by sparse_buffer_alloc then
annotate sparse_buffer_free with a matching annotation.
Downgrade the annotation to __meminit for both, as they may be
used in the hotplug case.
