This is a series of fixes addressing the issues in the way we handle - Self-Hosted trace filter control register for ETM/ETE - AUX buffer and event handling of TRBE at overflow. The use of TRUNCATED flag on an IRQ for the TRBE driver is something that needs to be rexamined. Please see Patch 3 for more details.
