Only two patches this time, both fixing issues introduced by the large irqdomain update during the merge window. One is a simple documentation update. The other is an interesting bug affecting MIPS, where we were able to perform irqdomain look-ups (which now implies using RCU at all times) without being in the right context (straight out of idle, for example). The issue was always there, we were just 'lucky' not to use RCU consistently in the irqdomain code... Please pull, M.
