Problem Details: Since the introduction of the fixes for the reorder timer, mac80211 will cause lockdep warnings because lockdep confuses local->skb_queue and local->rx_skb_queue and treats their lock as the same. However, their locks are different, and are valid in different contexts (the former is used in IRQ contex...

Problem Details: Now pps_idr_lock is never used in interrupt context so we can replace spin_lock_irq/spin_unlock_irq with plain spin_lock/spin_unlock.
