s390/bpf: correct broken uapi for BPF_PROG_TYPE_PERF_EVENT program type To mitigate and correct the broken uapi for the BPF_PROG_TYPE_PERF_EVENT program type, introduce a user_pt_regs structure (similar to arm64) that exports parts from the beginnig of the pt_regs structure. The export must start with the beginning of the pt_regs structure because to correctly calculate BPF prologues for perf (regs_query_register_offset()). For BPF_PROG_TYPE_PERF_EVENT program types, the BPF program is then passed a user_pt_regs structure. Note: Depending on future changes to the s390 pt_regs structure, consider the user_pt_regs structure to be stable for a particular kernel version only. (Of course, s390 tries to ensure keep it stable as much as possible.)
