Subject: [PATCH] fix compile failure with non modular builds

commit deac93df26b20cf8438339b5935b5f5643bc30c9

    lib: Correct printk %pF to work on all architectures

Broke the non modular builds by moving an essential function into
modules.c.  Fix this by moving it out again and into asm/sections.h as
an inline.  To do this, the definition of struct ppc64_opd_entry has
been lifted out of modules.c and put in asm/elf.h where it belongs.
