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 v2:
* Fixed tail call test case to handle the case where a called function is
  outside the 32-bit range of the BPF immediate field. Such calls are
  now omitted in this test. (13/13)
* Fixed typo in commit message. (7/13)
