Subject: [PATCH 2/6] ACPICA: acpiexec: Add option to specify an object initialization file.

From: Bob Moore <robert.moore@...el.com>

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.
