v2: https://lore.kernel.org/bpf/20240701133432.3883-1-iii@linux.ibm.com/
v2 -> v3: Fix bpf-gcc build issue.

v1: https://lore.kernel.org/bpf/20240627090900.20017-1-iii@linux.ibm.com/
v1 -> v2: Add a zero-extension fix.
          Fix wrong jump offset in the BPF_XCHG implementation.
          Do not run the UAF test on x86_64 and arm64.

Hi,

This series adds arena support to the s390x JIT.
Patch 1 is a common code fix, patches 2-5 are refactorings, patches 6-9
are the implementation, and patches 10-12 deal with testing.

Best regards,
Ilya
