[PATCH 3.12 026/123] ACPICA: Add "Windows 2013" string to _OSI support.

[Jiri Slaby]

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.
