As per include/asm-generic/vmlinux.lds.h and your arch's vmlinux.lds.S (I
actually only looked at x86's), the __initcall_{start,end} variables are the
start and end of the __initcall ELF section which contains all the sub-level
sections.
Functions can be put into these sections when they are given to one
of the *_initcall macros from include/linux/init.h.
