From 2dbb4c05d048995455857a7c2927a4297fc66c3b Mon Sep 17 00:00:00 2001 From: Michael Holzheu Date: Mon, 28 Nov 2016 13:48:30 +0100 Subject: bpf/samples: Fix PT_REGS_IP on s390x and use it 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".
