Subject: ARM: etm: Don't limit tracing to only non-secure code.
X-Git-Tag: v3.0.35-fsl~441
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=34de15a934a5751e7cdf9ebe5df8174d658e3268;p=karo-tx-linux.git

ARM: etm: Don't limit tracing to only non-secure code.

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.
