Patches 01 ~ 04 are preparasion patches which mainly resolve the issue for memory events, since the existed code is hard coded the memory events which based on x86 and PowerPC architectures, so patches 01 ~ 04 extend to support more flexible memory event name, and introduce weak functions so can allow every architecture to define its own memory events structure and returning event pointer and name respectively. Patch 05 is used to extend Perf memory tool to support AUX trace. Patch 06 ~ 11 are to support Arm SPE with Perf memory tool. Firstly it registers SPE events for memory events, then it extends the SPE packet to pass addresses info and operation types, and also set 'data_src' field so can allow the tool to display readable string in the result. This patch set has been tested on ARMv8 Hisilicon D06 platform. I noted now the 'data object' cannot be displayed properly, this should be another issue so need to check separately.
