commit 4ada1e810038e9dbc20e40b524e05ee1a9d31f98 upstream.
With gcc-4.6.3:
WARNING: vmlinux.o(.text.unlikely+0x140): Section mismatch in reference from the function populate_initrd_image() to the variable .init.ramfs.info:__initramfs_size The function populate_initrd_image() references the variable __init __initramfs_size. This is often because populate_initrd_image lacks a __init annotation or the annotation of __initramfs_size is wrong.
WARNING: vmlinux.o(.text.unlikely+0x14c): Section mismatch in reference from the function populate_initrd_image() to the function .init.text:unpack_to_rootfs() The function populate_initrd_image() references the function __init unpack_to_rootfs(). This is often because populate_initrd_image lacks a __init annotation or the annotation of unpack_to_rootfs is wrong.
WARNING: vmlinux.o(.text.unlikely+0x198): Section mismatch in reference from the function populate_initrd_image() to the function .init.text:xwrite() The function populate_initrd_image() references the function __init xwrite(). This is often because populate_initrd_image lacks a __init annotation or the annotation of xwrite is wrong.
Indeed, if the compiler decides not to inline populate_initrd_image(), a warning is generated.
Fix this by adding the missing __init annotations.
