It only affects 5.15. Bisection in progress.
I guess it will point to

tracing/kprobes: Return EADDRNOTAVAIL when func matches several symbols
It sure did!:
commit 7b4375c36a4c0e1b4b97ccbcdd427db5a460e04f
Author: Francis Laniel <flaniel@xxxxxxxxxxxxxxxxxxx>
Date: Fri Oct 20 13:42:49 2023 +0300
tracing/kprobes: Return EADDRNOTAVAIL when func matches several symbols
commit b022f0c7e404887a7c5229788fc99eff9f9a80d5 upstream.
Reverting that commit made the build pass again.
It looks like it depends on commit d721def7392a ("kallsyms: Make kallsyms_on_each_symbol
generally available"), but that doesn't apply cleanly.
