Ah, I was incorrectly assuming that TWD was referring to the architected
timers, sorry about that.

Maybe we should do this differently then and do the more logical

config LOCAL_TIMERS
	bool

config ARM_TWD
	bool "ARM TWD local timer"
	depends on SMP && CPU_V7
	select LOCAL_TIMERS

config EXYNOS4_MCT
	bool "Samsung Exynos4 MCT Timer"
	depends on SMP && ARCH_EXYNOS
	select LOCAL_TIMERS

config MSM_LOCAL_TIMER
	bool "Qualcomm MSM Local Timer"
	depends on SMP && ARCH_MSM
	select LOCAL_TIMERS

That way we have no implicit assumptions. Everything will still work if you
disable local timers, but of course we will enable them in the defconfigs.
