commit 8c106237ef4da972e3814acc197210267ed23751
Author: Timothy Pearson <tpearson at raptorengineeringinc.com>
Date:   Tue Feb 10 22:21:39 2015 -0600

    acpi: Generate valid ACPI processor objects
    
    The existing code generated invalid ACPI processor objects
    if the core number was greater than 9.  The first invalid
    object instance was autocorrected by Linux, but subsequent
    instances conflicted with each other, leading to a failure
    to boot if more than 10 CPU cores were installed.
    
    The modified code will function with up to 99 cores.
