legacy_printk selftests is specially designed to be runnable on old
kernels and validate libbpf's bpf_trace_printk-related macros. Run them
in CI.

A lot of tests in test_progs fail due to the missing trampoline
implementation on s390x (and a handful for other reasons). Yet, a lot
more pass, so disabling test_progs altogether is too heavy-handed.
So add a mechanism for arch-specific blacklists (as discussed in [1])
and introduce a s390x blacklist, that simply reflects the status quo.

Select the current config based on $ARCH value and thus rename
the existing config to config-latest.$ARCH.

There is a problem in bpf-next tree which causes get_stack_raw_tp and
few other selftests to produce tons of kernel warnings, timing out and
failing CI test runs. Blacklist until bpf tree, which has a fix, is
merged into bpf-next.

Use this list of enabled tests as a whitelist, so that we don't have to
keep updating BLACKLIST-5.5.0 anymore. I'll keep BLACKLIST-5.5.0 for
now, because it serves as a nice historic log of which tests depend on
which kernels.

Add few new selftests to blacklist. They can't succeed on 5.5.
Also temporarily remove btf_dump for 4.9 due to newly added data dumping
subtests.

Temporary disable tc_bpf tests that seem to have regressed.
Temporary and artificially bump pahole version from 1.21 to 1.22 to get
per-CPU BTF data built.

It requires v5.9+ kernel when the test code is built with a newer
toolchain. The support was added by commit b33164f2bd1c ("bpf:
Iterate through all PT_NOTE sections when looking for build id").

test_progs's IMA selftests requires extra Kconfig values, so update
latest.config to accommodate those.

tcpbpf_user uses cgroup bpf_link, not available in 5.5. hash_large_key is
testing a more permissive verifier check, implemented in 5.11. So blacklist
both.

Blacklist new tests that are depending on features in latest kernel. Also
temporarily blacklist raw_tp_test_run test, until it is fixed upstream.

Blacklist btf_map_in_map permanently for 5.5. bpf_verif_scale is broken due to
Clang issues on latest. Do not run ALU32 flavor for test_progs on 4.9.0, which
doesn't support ALU32 yet.

Drop blacklist and instead use a small whitelist of tests that are still
supposed to work on old 4.9 kernel.

Make sure that libbpf sanitizes BTF properly for older kernels.
Add a stage for 4.9.0 kernel in TravisCI.
For now make test failures non-blocking by adding 4.9.0 to `allow_failures`
section.
Blacklist is copy-pasted 5.5.0 kernel blacklist.
Now that pre-generated vmlinux.h is used for compilation of non-latest tests,
we don't need custom adjustments for 5.5 kernel selftests. Adjust blacklist
now that those new self-tests are built into test_progs.

Manually generate vmlinux.h based on latest.config to be used for non-latest
selftest build. This will keep bpftool and newest selftests builds succeeding,
while at runtime blacklist will skip them.

Permanently blacklist load_bytes_relative test on 5.5 due to missing
functionality.
Also temporarily blacklist core_reloc test due to failure on latest kernel.
