Since a while booting a PS3 instantly yields:

Can you bisect to say since when, and add a Fixes: tag to the commit ?

I could, but it might take a day, or two. But maybe always, and we
only notice since 6eaaf9de3599865ee3b339d90cb24f2153f40bf4
("powerpc/64s/interrupt: Check and fix srr_valid without crashing")?

Should I use that as a Fixes?

Instead, use:

Of course, happy to v2 as soon as I know of the above Fixes: is good
enough or I should start bisecting to double-check, ...
