This patch is originally based on commit b3377d186572 (ARM: 7064/1: vexpress: Use wfi macro in platform_do_lowpower.) Current Exynos 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

As per commit b3377d186572 (ARM: 7064/1: vexpress: Use wfi macro in platform_do_lowpower.), wfi macro should be used instead of the hardcoded WFI instruction. This fixes following oops when the kernel is compiled in Thumb-2 mode on EXYNOS5. (Tested on EXYNOS5250 based Arndale board) $ reboot
