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.
Gentle ping ...

It would be appreciate if can get some review for this patch set.
I was hoping that James Clark would have a look, since he was the last
person to go near the userspace side of SPE.
Yes, I have offline synced with James and James has verified this
patch set at his side.

I don't want to rush to ask Arnaldo to merge patches, so just
want to get wider reviewing if possible; otherwise, I will rebase this
patch set and resend to ML.

Thanks,
Leo
