Some massaging was needed here to make these apply against the
RCU changes in git-sched.

All fairly simple, except I don't know if these:

static inline void rcu_enter_nohz(void)
{
	smp_mb(); /* CPUs seeing ++ must see prior RCU read-side crit sects */
	__get_cpu_var(rcu_dyntick_sched).dynticks++;
	WARN_ON(__get_cpu_var(rcu_dyntick_sched).dynticks & 0x1);
}

static inline void rcu_exit_nohz(void)
{
	__get_cpu_var(rcu_dyntick_sched).dynticks++;
	smp_mb(); /* CPUs seeing ++ must see later RCU read-side crit sects */
	WARN_ON(!(__get_cpu_var(rcu_dyntick_sched).dynticks & 0x1));
}

in include/linux/rcupreempt.h ended up the way we want them?
