torture: Stop hanging on panic
By default, the "panic" kernel parameter is zero, which causes the kernel to loop indefinitely after a panic(). The rcutorture scripting will eventually kill the corresponding qemu process, but only after waiting for the full run duration plus a few minutes. This works, but delays notifying the developer of the failure. This commit therefore causes the rcutorture scripting to pass the "panic=-1" kernel parameter, which caused the kernel to instead unceremoniously shut down immediately. This in turn causes qemu to terminate, so that if all of the runs in a given batch panic(), the rcutorture scripting can immediately proceed to the next batch. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
