And this point I'm not sure I'm following. Why exactly does disabling 
ARCH_USES_GETTIMEOFFSET cause boot failures? Could you expand on the 
details here?

You should just end up using the jiffies clocksource, which would give 
you low-res HZ granular timestamps, but shouldn't get in the way of booting.
