>> WARNING: modpost: vmlinux.o(.text+0xb8b8): Section mismatch in reference from the function reserve_exception_space() to the function .meminit.text:memblock_reserve()
The function reserve_exception_space() references
the function __meminit memblock_reserve().
This is often because reserve_exception_space lacks a __meminit
annotation or the annotation of memblock_reserve is wrong.
