v1: https://lore.kernel.org/bpf/20230830011128.1415752-1-iii@xxxxxxxxxxxxx/ 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.
