Please see patch 1 for the explanation of the problem.
Patch 2 adds a test so that we don't regress.

v1 -> v2:
- switch from __attibute__((always_unused)) to unused to avoid CI failures.

Jakub Sitnicki (2):
  bpf, x86: Fix tail call count offset calculation on bpf2bpf call
  selftests/bpf: Test tail call counting with bpf2bpf and data on stack
