From ccd3dbcbf1c62610d455222e6da11397d502c582 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Arve=20Hj=C3=B8nnev=C3=A5g?= Date: Fri, 28 Jan 2011 23:33:11 -0800 Subject: [PATCH 267/696] ARM: etm: Don't limit tracing to only non-secure code. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit On some systems kernel code is considered secure, and this code already limits tracing to the kernel text segment which results in no trace data.
