It turns out that although PIIX4 hardware defines the S5 type code to be 000, all OSes will discover the correct code by evlauating an \_Sx object in the ACPI DSDT. And we set the type code in that object to be 111. So this patch keeps the other cleanups made to the piix4acpi.c file, but switches back to checking for code 111. It also makes it clearer in both the ioemu code and in the dsdt source code where these magic numbers come from. Let's hope noone actually has the true PIIX4 type codes hardcoded (it's highly doubtful that anyone would). Signed-off-by: Keir Fraser <keir@xensource.com>
