[ARM] 4494/1: iop13xx: fix up elf_hwcap compile breakage
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:
f884b1cf578e079f01682514ae1ae64c74586602
d1cbbd6b413510c6512f4f80ffd48db1a8dd554a
include/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().
