I'm really sorry for introducing the failure. I would suggest to add aarch64 as well. 

Actually, I can't enable the GH action with my account. Every time I enable the Pre-submit tests workflow, my account will be suspended by GitHub. That's how I lost my first OpenJDK account, https://github.com/faye-arm. I sent requests to GitHub Support team multiple times, but got the reply, _Any future contact about this suspension may be closed without response_. @shipilev , could you please tell me how I can fix the issue about GH action, or if I can have another way to enable pre-submit tests? Thanks very much.
