* perf/x86/intel/uncore: Clean up hardware on exitThomas Gleixner2016-02-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | When tearing down the boxes nothing undoes the hardware state which was setup by box->init_box(). Add a box->exit_box() callback and implement it for the uncores which have an init_box() callback. This misses the cleanup in the error exit pathes, but I cannot be bothered to implement it before cleaning up the rest of the driver, which makes that task way simpler.

* perf/x86/intel/uncore: Fix error handlingThomas Gleixner2016-02-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | This driver lacks any form of proper error handling. If initialization fails or hotplug prepare fails, it lets the facility with half initialized stuff around. Fix the state and memory leaks in a first step. As a second step we need to undo the hardware state which is set via uncore_box_init() on some of the uncore implementations.

| | | | | | | | | | | | | | | | | | | | | | | | | No point in doing partial rollbacks.
