MID has no PIC, but depending on the platform it requires the abt_timer, which is connected to irq0. The timer is set up at late_time_init(). But, looking at the MID code it seems, that there is no reason to do so. The only code which might need the timer working is the TSC calibration code, but thats a non issue on MID as that is using its own empty calibration function. And check_timer() is not invoked either because MID has no PIC and therefor no legacy irqs. So if you look at intel_mid_time_init() then you'll see that in the ARAT case the timer setup is skipped already. So until the point where x86_init.timers.setup_percpu_clockev() is called for the boot cpu nothing really needs a timer on MID. According to the MID code the apbt horror is only used for moorestown. Medfield and later use the local apic timer without the apbt nonsense. The best thing we can do is to drop moorestown support and get rid of that apbt nonsense alltogether. I don't think anyone deeply cares about it not being supported from 3.18 on. The number of devices which sport a moorestown should be pretty limited and the only relevant use case of those is to act as a pocket heater with short battery life time. Its pretty pointless to update kernels on pocket heaters except for bragging reasons. If someone at Intel really thinks that we need to keep moorestown alive for other than documentary and sentimental reasons, then we can move the apbt setup to x86_init.timers.setup_percpu_clockev(). At that point the IOAPIC is setup already, so it should just work.
