From: Bob Moore <robert.moore@xxxxxxxxx>
This option (-fi) allows the specification of a file that is used
to specify initialization values for individual namespace objects.
Each line in the file is in the format:
<ACPI pathname> <Integer Value>
This patch only affects acpiexec which is not in the Linux kernel.
