Subject: [PATCH] ACPI: add missing _OSI strings
Linux supports some optional features, but it should notify the BIOS about
them via the _OSI method. Currently Linux doesn't notify any, which might
make such features not work because the BIOS doesn't know about them.
Jarosz has a system which needs this to make ACPI processor aggregator
device work.
