We like living dangerously. Nothing explicitely forbids stack-protector to be used in the EL2 code, while distributions routinely compile their kernel with it. We're just lucky that no code actually triggers the instrumentation. Let's not try our luck for much longer, and disable stack-protector for code living at EL2.
