From cde3f8607350666c4dd120dbbdbd9c70ffb2ea61 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Tue, 13 Oct 2009 08:54:30 +0100 Subject: ARM: 5759/1: Add register information of threads to coredump Defines ELF_CORE_COPY_TASK_REGS so that CPU register information of every thread is included in coredump. Without this, only the faulting thread is coredumped.
