Back when the patch was submitted for "Add Xeon 7500 series support to
oprofile", Robert Richter had asked for a follown patch that converted
all the CPU ID values to hex.
I have done that here for the processors in the ppro_init() function and also
added some documentation as comments that I retrieved from the Intel Software
Developer's Manual (SDM) March 2010 edition in Volume 3B, Table B-1.
The Intel SDM can be found at:
http://www.intel.com/products/processor/manuals/
I also added processor codenames for some of the newer processors.
