With binutils 2.24, various 64 bit builds fail with relocation errors such as arch/powerpc/kernel/built-in.o: In function `exc_debug_crit_book3e': (.text+0x165ee): relocation truncated to fit: R_PPC64_ADDR16_HI against symbol `interrupt_base_book3e' defined in .text section in arch/powerpc/kernel/built-in.o arch/powerpc/kernel/built-in.o: In function `exc_debug_crit_book3e': (.text+0x16602): relocation truncated to fit: R_PPC64_ADDR16_HI against symbol `interrupt_end_book3e' defined in .text section in arch/powerpc/kernel/built-in.o The assembler maintainer says: I changed the ABI, something that had to be done but unfortunately happens to break the booke kernel code. When building up a 64-bit value with lis, ori, shl, oris, ori or similar sequences, you now should use @high and @higha in place of @h and @ha. @h and @ha (and their associated relocs R_PPC64_ADDR16_HI and R_PPC64_ADDR16_HA) now report overflow if the value is out of 32-bit signed range. ie. @h and @ha assume you're building a 32-bit value. This is needed to report out-of-range -mcmodel=medium toc pointer offsets in @toc@h and @toc@ha expressions, and for consistency I did the same for all other @h and @ha relocs. Replacing @h with @high in one strategic location fixes the relocation errors. This has to be done conditionally since the assembler either supports @h or @high but not both.
