MWAIT binds to the same IP as a subsequent EXSTOP.

We had enqueued MWAIT on the next FUP.  Change this to enqueue MWAIT on
EXSTOP and then on the next FUP - depending on whether EXSTOP has the IP bit
set.

This is closer to the spec and supports the case of a standalone EXSTOP.

Intel(R) Processor Trace Decoder Library
========================================

The Intel Processor Trace (Intel PT) Decoder Library is Intel's reference
implementation for decoding Intel PT.  It can be used as a standalone library or
it can be partially or fully integrated into your tool.

The library comes with a set of sample tools built on top of it and a test
system built on top of the sample tools.  The samples demonstrate how to use the
library and may serve as a starting point for integrating the library into your
tool.

Dependencies
------------

We use cmake for building.

  cmake         The cross-platform open-source build system.
                http://www.cmake.org


Other packages you need for some of the above optional components.

  xed           The Intel x86 instruction encoder and decoder.
                https://github.com/intelxed/xed

                This is needed to build and run ptxed.

  yasm          The Yasm Modular Assembler
                http://github.com/yasm

                This is needed to run pttc.

  pandoc        A universal document converter
                http://pandoc.org

                This is needed for man pages.
