This set enables BPF_PROG_TEST_RUN for raw_tracepoint type programs. This set also enables running the raw_tp program on a specific CPU. This feature can be used by user space to trigger programs that access percpu resources, e.g. perf_event, percpu variables. Changes v2 => v3: 1. Fix memory leak in the selftest. (Andrii) 2. Use __u64 instead of unsigned long long. (Andrii) Changes v1 => v2: 1. More checks for retval in the selftest. (John) 2. Remove unnecessary goto in bpf_prog_test_run_raw_tp.
