Merge branch 'modversions' (modversions fixes for powerpc from Ard)
Merge kcrctab entry fixes from Ard Biesheuvel:
"This is a followup to [0] 'modversions: redefine kcrctab entries as
relative CRC pointers', but since relative CRC pointers do not work in
modules, and are actually only needed by powerpc with
CONFIG_RELOCATABLE=y, I have made it a Kconfig selectable feature
instead.
First it introduces the MODULE_REL_CRCS Kconfig symbol, and adds the
kbuild handling of it, i.e., modpost, genksyms and kallsyms.
Then it switches all architectures to 32-bit CRC entries in kcrctab,
where all architectures except powerpc with CONFIG_RELOCATABLE=y use
absolute ELF symbol references as before"

* emailed patches from Ard Biesheuvel:
module: unify absolute krctab definitions for 32-bit and 64-bit
modversions: treat symbol CRCs as 32 bit quantities
kbuild: modversions: add infrastructure for emitting relative CRCs
