Repeated the same tests as the upstream code on top of v5.10.14 and v5.9.16, tested on powerpc64 and powerpc64le, with a glibc build and running the affected glibc's testcase[2], inspected that glibc's backtrace() now gives the correct result and gdb backtrace also keeps working as before.
I believe this should be backported to releases 5.9 and 5.10 as userspace is affected in this releases. I hope I had tagged this correctly in the patch.
Now added to 5.10.y, 5.9.y is long end-of-life so there is nothing we can do there, sorry.
No problem, I didn't know 5.9.y was already EOL, that is on me.
Hint, in the future www.kernel.org shows you this :)
