* drivers/hwtracing: make coresight-etm-perf.c explicitly non-modularPaul Gortmaker2016-03-051-2/+2
| | | | | | | | | | | | | | | | | | | | In commit 941943cf519f7cacbbcecee5c4ef4b77b466bd5c ("drivers/hwtracing: make coresight-* explicitly non-modular") we removed all uses of modular functions/macros in favour of their built-in equivlents in this subsystem. However that commit and commit 0bcbf2e30ff2271b54f54c8697a185f7d86ec6e4 ("coresight: etm-perf: new PMU driver for ETM tracers") were in flight at the same time, and hence one new non-modular user of module_init crept back in. Fix it up like we did all the others. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit.

* coresight: etm-perf: new PMU driver for ETM tracersMathieu Poirier2016-02-201-0/+393
Perf is a well known and used tool for performance monitoring and much more. A such it is an ideal candidate for integration with coresight based HW tracing. This patch introduces a PMU that represent a coresight tracer to the Perf core.
