This patch reworks the Linux Kernel panic and oops events. The code has been re-factored to provide re-usable events that can be applied to all ISAs from the base `KernelWorkload` `SimObject`. At the moment they are installed for the Arm workloads. This update also provides more configuration options that can be specified using the new `KernelPanicOopsBehaviour` enum. The options are applied to the Kernel Workload parameters `on_panic` and `on_oops` which are available to all subclasses of `KernelWorkload`. The main rationale for this reworking is to add the option to cleanly exit the simulation after dumping the Dmesg buffer. Without this option, the simulation would continue running after a Kernel panic. If system components (e.g. a system timer) keep the event queue alive, this causes the simulation to run slowly to the maximum allowed tick.
