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.
