If mach-exynos would support ARMv8 at some point, I would expect most
of the code to go under various drivers/ subsystems (mfd, power etc.).
I don't see any point in using opcodes. For wfi just use a macro or
cpu_do_idle() (as Rob said, it does the required dsb as well).
I'm also pushing for a standard hotplug.c implementation that is
shared by multiple platforms and uses the power state coordination
interface implemented by the firmware.
