From: Bob Moore <Robert.Moore@xxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit faae404ebdc6bba744919d82e64c16448eb24a36 upstream.
This urgent patch is cherry picked from ACPICA upstream.
It is reported that some platforms fail to boot without this new _OSI
string.
This change adds this string for Windows 8.1 and Server 2012 R2.
