This patch set extends the eBPF test suite in the test_bpf kernel module
to add more extensive tests of corner cases and new tests for operations
not previously covered.

An RFC patch set was previously submitted.

Link: https://lore.kernel.org/bpf/20210726081738.1833704-1-johan.almbladh@anyfinetworks.com/

Changes from RFC patch set:

* Changed tail call count limit test to comply with the new behavior of
  the interpreter, i.e. at most MAX_TAIL_CALL_CNT tail calls are
  permitted.

* Fixed an uninitilized variable in tail call test error path, found by
  the Kernel test robot. Also fixed a warning due to pointer-to-u32 cast
  in IMM64 load instructions.

The checkpatch.pl script reports an error for the multi-line macro in
patch 14/14 ("bpf/tests: Add tail call test suite"). However, it cannot
be enclosed in parenthesis as suggested since it is an array element
initialization, similar the existing BPF_LD_IMM64() helper macro. It can
be replaced, but I do think the code and the intent is clearer this way.

Thanks,
Johan
