No worries! I've made the change locally and will push this out to
-next unless there are objections?

I'm a bit wary of conflicts in entry.S, since it's likely that we're going
to have a lot going on in there for 4.19.

Could I take this via arm64 instead, please, or are there dependencies
on other parts of your tree?

It depends on the plugin existing, but we could split it up so the
arm64 part could go separately. It would just be a no-op in the arm64
tree since CONFIG_GCC_PLUGIN_STACKLEAK won't exist there. Whatever
works best for you!

-Kees
