Adding Frederic on CC...
I am dropping these three for the moment:
0ba8896d2fd75 lib/irq_poll: Declare IRQ_POLL softirq vector as ksoftirqd-parking safe
efa8027149a1f tick/rcu: Stop allowing RCU_SOFTIRQ in idle
d338d22b9d338 tick/rcu: Remove obsolete rcu_needs_cpu() parameters
Though it might be that these are victims of circumstance, in other
words, that the original bug that Paul Menzel reported was caused by
something else.
Thanx, Paul
