    Subject[41/59] Oprofile: Change CPUIDS from decimal to hex, and add some comments
    2.6.32-stable review patch.  If anyone has any objections, please let us know.

    ------------------

    From: John Villalovos <sodarock@gmail.com>

    commit 45c34e05c4e3d36e7c44e790241ea11a1d90d54e upstream.

    Back when the patch was submitted for "Add Xeon 7500 series support to
    oprofile", Robert Richter had asked for a followon patch that
    converted all the CPU ID values to hex.

    I have done that here for the "i386/core_i7" and "i386/atom" class
    processors in the ppro_init() function and also added some comments on
    where to find documentation on the Intel processors.
