Mike Leach 096dcfb9cd coresight: etm4x: Ensure default perf settings filter user/kernel ... Moving from using an address filter to trace the default "all addresses" range to no filtering to acheive the same result, has caused the perf filtering of kernel/user address spaces from not working unless an explicit address filter was used. This is due to the original code using a side-effect of the address filtering rather than setting the global TRCVICTLR exception level filtering. The use of the mode sysfs file is also similarly affected. A helper function is added to fix both instances.
