arch/arm/boot/compressed/misc.o: In function `valid_user_regs': misc.c:(.text+0x74): undefined reference to `elf_hwcap' This triggers after the various elf_hwcap cleanups in:f884b1cf57d1cbbd6b41include/asm-arm/arch-iop13xx/uncompress.h calls cpu_relax while spinning on a register value. cpu_relax requires processor.h->ptrace.h->hwcap.h 'elf_hwcap' is defined as an extern, but since the uncompressor does not link against arch/arm/kernel/setup.c 'elf_hwcap' remains undefined. Fix is to open code the cpu_relax() call as barrier().
