[PATCH stable 5.15 0/1] bpf: Fix map poke update

[Jiri Olsa <jolsa@kernel.org>]

hi,
sending the 5.15 backport of map poke update fix [1].

It's not straight backport, the details are in changelog. I also backported
the bpf selftest [2] to reproduce the issue and verify the fix, but it's more
deviated from the upstream so I decided not to post it. Also I had to fix bpf
selftests on other place to be able to compile them.

thanks,
jirka
