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" [0] http://marc.info/?l=linux-arch&m=148493613415294&w=2 * 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
