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).
