It could. HIGH_RES_TIMERS is useful and IRQ_FORCED_THREADING is
required. You already have PREEMPT(ION) which is good. Then you would
have to try and my guess would be that some of spinlock_t vs
raw_spinlock_t could require changes but we should have lockdep support
for that which would make things easier.
