Subject: ARM: etm: Don't limit tracing to only non-secure code.
X-Git-Tag: firefly_0821_release~4090^2~814

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.
