From d912557b346099584bbbfa8d3c1e101c46e33b59 Mon Sep 17 00:00:00 2001 From: Michael Holzheu Date: Mon, 6 Jul 2015 16:20:07 +0200 Subject: samples: bpf: enable trace samples for s390x The trace bpf samples do not compile on s390x because they use x86 specific fields from the "pt_regs" structure. Fix this and access the fields via new PT_REGS macros. Signed-off-by: Michael Holzheu Acked-by: Alexei Starovoitov Signed-off-by: David S.
