bpf/samples: Fix PT_REGS_IP on s390x and use it

2016-11-28T21:26:46Z

The files "sampleip_kern.c" and "trace_event_kern.c" directly access "ctx->regs.ip" which is not available on s390x. Fix this and use the PT_REGS_IP() macro instead. Also fix the macro for s390x and use "psw.addr" from "pt_regs". Reported-by: Zvonko Kosic Signed-off-by: Michael Holzheu Acked-by: Alexei Starovoitov Signed-off-by: David S. Miller
