v1: https://lore.kernel.org/bpf/20230830011128.1415752-1-iii@linux.ibm.com/
v1 -> v2:
- Redo Disable zero-extension for BPF_MEMSX as Puranjay and Alexei
  suggested.
- Drop the bpf_ct_insert_entry() patch, it went in via the bpf tree.
- Rebase, don't apply A-bs because there were fixed conflicts.

Hi,

This series adds the cpuv4 support to the s390x eBPF JIT.
Patches 1-3 are preliminary bugfixes.
Patches 4-8 implement the new instructions.
Patches 9-10 enable the tests.

Best regards,
Ilya
