Please merge commit 4f2c7583e33e irqchip/gic-v3-its: Ensure nr_ites >= nr_lpis into -stable v4.14 - v4.15 It fixes a bug in the GICv3 interrupt controller driver that only gets triggered on systems with unusual PCIe topologies, but it is a bug nonetheless. I will send out a separate backport to v4.9, which needs a trivial tweak to unrelated context for it to apply cleanly.
