Subject[PATCH 0/3] ARC: ARCv2: Introduce SmaRT support
Date
Add compile-time 'ARC_SMART_TRACE' option for enabling SmaRT support.
Small real time trace (SmaRT) is an optional on-chip debug hardware
component that captures instruction-trace history. It stores the
address of the most recent non-sequential instructions executed into
internal buffer.

NOTE:
this PATCH series has prerequisite:
http://patchwork.ozlabs.org/patch/986820/

Changes RFCv2->PATCHv1:
* Move smart_exists, smart_supported and smart_stack_size functions
to smart.h
* Improve Kconfig SmaRT help description.
* Other minor changes.

Changes RFCv1->RFCv2:
* Changes in output display:
* Only print VMAs if they are changed.
* Split entry for two lines and print source and destination
addresses on different lines.
* Add procfs options to configure/suspend SmaRT in runtime.
* Add SmaRT version check. Limit supported SmaRT versions to >= 0x03.
* Move all SmaRT related stuff to smart.h and smart.c
* Other minor changes.
