.mailmap version in the upstream repository.

github.head_ref is empty for push and schedule events, so all those
runs shared the same concurrency group and cancelled each other. Fall
back to github.run_id to give each non-PR run a unique group.

The libbpf CI always builds the kernel from source at CHECKPOINT-COMMIT;
there is no prebuilt-kernel matrix entry. Remove the `kernel` input and
the conditional build-vs-download logic, simplifying the workflow.
The run-vmtest action defaults KERNEL to "LATEST" internally when the
env var is unset, so DENYLIST-LATEST is still picked up. The vmlinuz
path is auto-discovered via `make -s image_name` when not passed.

Merge DENYLIST-LATEST into DENYLIST and remove the per-kernel denylist
files. With LATEST being the only kernel mode, there's no need for
separate files. Also remove the s390x denylist (libbpf CI only tests
x86_64) and drop stale entries fixed upstream.
Add map_kptr, test_profiler (kprobes not available in VM kernel), and
sockmap udp multi channels (flaky) based on CI run results.

All 4 patches either fail to apply (context mismatch) or are already
applied upstream. They produce noise in CI logs.

Implement bpf_stream_vprintk with an implicit bpf_prog_aux argument,
and remote bpf_stream_vprintk_impl from the kernel.
Update the selftests to use the new API with implicit argument.
bpf_stream_vprintk macro is changed to use the new bpf_stream_vprintk
kfunc, and the extern definition of bpf_stream_vprintk_impl is
replaced accordingly.

Add the following functions to libbpf API:
* btf__add_type_attr()
* btf__add_decl_attr()
These functions allow to add to BTF the type tags and decl tags with
info->kflag set to 1. The kflag indicates that the tag directly
encodes an __attribute__ and not a normal tag.
See Documentation/bpf/btf.rst changes in the subsequent patch for
details on the semantics.

run-on-arch-action is simply a wrapper around docker. There is no
value in using it in libbpf, as it is not complicated to run
non-native arch docker images directly on github-hosted runners.
Docker relies on qemu-user-static installed on the system to emulate
different architectures.
Recently there were various reports about multi-arch docker builds
failing with seemingly random issues, and it appears to boil down to
qemu [1]. I stumbled on this problem while updating s390x runners [2]
for BPF CI, and setting up more recent version of qemu helped.
This change addresses recent build failures on s390x and ppc64le.
