| |
From: Michael Holzheu <holzheu@linux.vnet.ibm.com>
On s390 we have the possibility to configure actions that are executed in case of a kernel panic. E.g. it is possible to automatically trigger an s390 stand-alone dump. The actions are called via a panic notifier. We also want to trigger kdump via the notifier call chain. Therefore this patch disables for s390 the direct kdump invocation in the panic() function.
