WARNING: vmlinux.o(.text.unlikely+0x650): Section mismatch in reference from the function free_memmap() to the function .meminit.text:memblock_free()
The function free_memmap() references
the function __meminit memblock_free().
This is often because free_memmap lacks a __meminit 
annotation or the annotation of memblock_free is wrong.
