clang sometimes decides not to inline shuffle_zone(), but it calls a __meminit function. Without the extra __meminit annotation we get this warning: WARNING: modpost: vmlinux.o(.text+0x2a86d4): Section mismatch in reference from the function shuffle_zone() to the function .meminit.text:__shuffle_zone() The function shuffle_zone() references the function __meminit __shuffle_zone(). This is often because shuffle_zone lacks a __meminit annotation or the annotation of __shuffle_zone is wrong. shuffle_free_memory() did not show the same problem in my tests, but it could happen in theory as well, so mark both as __meminit.
