[PATCH 00/10] Extensions for PTWRITE

[felix.willgerodt@intel.com]

From: Felix Willgerodt <felix.willgerodt@intel.com>

Hi all,

this is a set of patches extending the GDB record functionality for the new
x86 instruction PTWRITE.  PTWRITE allows the user to write any value into
the Intel Processor Trace.  This patch series enables the user to access,
store and display these values in GDB/Python.

Regards,
Felix
