Hi Tom:
Thanks for your test. Could you help to test the following
patch and check whether it can fix the issue.
The patch is mangled. Is the only difference where
set_memory_decrypted() is called?
I de-mangled the patch. No more stack traces with SME active.
Thanks,
Tom
Hi Tom:
Thanks a lot for your rework and test. I will update in the next
