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.
