Current Versatile Express CPU hotplug code includes a hardcoded WFI instruction, in ARM encoding. When the kernel is compiled in Thumb-2 mode, this is invalid and causes the machine to hang hard when a CPU is offlined. Using the wfi macro (which uses the appropriate assembler mnemonic) causes the correct instruction to be emitted in either case. As a consequence of this change, an apparently vestigial "cc" clobber is dropped from the asm (the macro uses "memory" only).
