Hi, this is your Linux kernel regression tracker. CCing the regression
mailing list, as it should be in the loop for all regressions:

FWIW, that's 994b7ac1697b ("arm64: remove special treatment for the link
order of head.o") from Masahiro merged through Will this cycle.

Makes me wonder if other distros or CIs relying on the build-id are
broken, too.

Anyway, the holiday season is upon us, hence I also wonder if it would
be best to revert above change quickly and leave further debugging for 2023.

Masahiro, Will, what's your option on this?

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.
