Subject: [PATCH bpf-next v2 00/13] bpf/tests: Extend JIT test suite coverage

This patch set adds a number of new tests to the test_bpf.ko test suite.
The tests are intended to verify the correctness of eBPF JITs.

Changes since v1:
* Fixed ASCII diagram of staggered jump test pattern (6/13).
* Fixed R0 initialization issue found by kbuild CI. Add comment on
  diagnostics/debugging instead of setting R0 to the current
  instruction index (3,4,7/13).
