From 90407c9976939e061f32b0e07602e5ce4887d9e8 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Mon, 21 Mar 2011 10:57:57 +1100 Subject: powerpc/pci: Fix crash in PCI code on ppc64 when matching device nodes Commit b5d937de0367d26f65b9af1aef5f2c34c1939be0 has a bug which causes basically a NULL dereference in the PCI code during boot on ppc64 machines. fetch_dev_dn() is called when dev->dev.of_node is NULL, so using that as the starting point for the search makes no sense. It should instead start from the device node of the PHB.

This happens when the signal causing the core dump races with a thread exiting. The race happens when the exiting thread has entered the kernel for the last time before the signal arrives, but doesn't get far enough through the exit code to avoid being included in the core dump. So we get a thread included in the core dump which is never going to go out to userspace again and only has a partial register set recorded Normally we would catch each thread as it is about to go into userspace and capture the full register set then. However, this exiting thread is never going to go out to userspace again, so we have no way to capture its full register set. It doesn't really matter, though, as this is a thread which is effectively already dead. So instead of hitting a BUG() in this case (a really bad choice of action in the first place), we use a poison value for the register values.

To run the connection reset function only in case of a crashdump, the is_kdump_kernel() function needs to be available for the PV driver modules.
