[S390] kernel: Shutdown Actions Interface
In case of a kernel panic it is currently possible to specify that a dump should be created, the system should be rebooted or stopped. Virtual sysfs files under the directory /sys/firmware/ are used for that configuration. In addition to that, there are kernel parameters 'vmhalt', 'vmpoff' and 'vmpanic', which can be used to specify z/VM commands, which are automatically executed in case of halt, power off or a kernel panic. This patch combines both functionalities and allows to specify the z/VM CP commands also via sysfs attributes. In addition to that, it enhances the existing handling of shutdown triggers (e.g. halt or panic) and associated shutdown actions (e.g. dump or reipl) and makes it more flexible.
