From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: initramfs: fix another section mismatch
Building with gcc-10 causes a harmless warning, similar to the gcc-4.6
warning that Geert fixed last year:
WARNING: modpost: vmlinux.o(.text.unlikely+0xe69): Section mismatch in reference from the function kexec_free_initrd() to the function .init.text:free_initrd_mem()
The function kexec_free_initrd() references
the function __init free_initrd_mem().
This is often because kexec_free_initrd lacks a __init
annotation or the annotation of free_initrd_mem is wrong.
Add the missing __init annotations.

Fixes: 4ada1e810038 ("initramfs: fix populate_initrd_image() section mismatch")
Fixes: 23091e287355 ("initramfs: cleanup initrd freeing")
