From aa165971c2923d05988f920c978e438dbc7b0de6 Mon Sep 17 00:00:00 2001 From: Shaohua Li Date: Thu, 28 Jul 2011 13:48:43 -0700 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.
