This patch set is to support synthetic events with enabling Arm SPE decoder. Since before Xiaojun Tan (Hisilicon) and James Clark (Arm) have contributed much for this task, so this patch set is based on their privous work and polish for the version 7.
The main work in this version is to polished the core patch "perf arm-spe: Support synthetic events", e.g. rewrite the code to calculate ip, packet generation for multiple types (L1 data cache, Last level cache, TLB, remote access, etc). It also heavily refactors code for data structure and program flow, which removed unused fields in structure and polished the program flow to achieve neat code as possible.
This patch set has been checked with checkpatch.pl, though it leaves several warnings, but these warnings are delibarately kept after reviewing. Some warnings ask to add maintainer (so far it's not necessary), and some warnings complaint for patch 02 "perf auxtrace: Add four itrace options" for the text format, since need to keep the consistency with the same code format in the source code, this is why this patch doesn't get rid of checkpatch warnings.
