Russell King 02088d9b39 ARM: net: bpf: fix register saving ... When an eBPF program tail-calls another eBPF program, it enters it after the prologue to avoid having complex stack manipulations. This can lead to kernel oopses, and similar. Resolve this by always using a fixed stack layout, a CPU register frame pointer, and using this when reloading registers before returning.
