I'm dropping the relevant patch from Andi's tree due to it causing
mysterious hangs when initscripts start ondemand. So I'll need to drop
this patch and "[patch 19/20] Add a sched_clock paravirt_op".
I still need to work out why that hang is happening - it is very
mysterious. I got as far as working out that it was hanging on
write_seqlock_irqsave(xtime_lock), then remembered that it's with
CONFIG_SMP=n so I stomped off to bed in disgust. Later.
