commit 69acd9af04be3ab3630663796e2c676ac509e055
Author: Edward O'Callaghan <eocallaghan at alterapraxis.com>
Date:   Sat May 31 13:57:52 2014 +1000

    amd/agesa,cimx: Rename ACPI OS detection methods
    
    Try to 'standardize' the otherwise peculiar method naming to be somewhat
    more in-line with other ACPI implementations. This makes it easier to
    compare with vendor DSDT dumps for example.
