This patch adds the required mechanic to quickly lookup the CPU number
associated with a traceID. That way the CPU that executed the code
conveyed by a decoded packet can be identified, without having to
do unecessary translations.
Using this new functionality the "cs-trace-disasm.py" script is
enhanced to output the file and CPU number the code has been
executed on:
