4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Dick Kennedy <dick.kennedy@xxxxxxxxxxxx> commit 1901762f2ca2747ed269239ca5332a8023ce4e3d upstream. During pci hot plug, the kernel crashes in timer management code. The sli4 remove_one handler is not stoping the timers as it starts to remove the port so that it can be swapped. Fix: Stop the timers early in the handler routine. Note: Fix in SLI-4 only. SLI-3 already stopped the timers properly.
