Subject: [PATCH 3.13 096/212] ACPI: blacklist win8 OSI for Dell Inspiron 7737

3.13.11.4 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Edward Lin <yidi.lin@...onical.com>

commit b753631b3576bf343151a82513c5d56fcda1e24f upstream.

With win8 capabiltiy, the machine will boot itself immediately after
shutdown command has executed.

Work around this issue by disabling win8 capcability.  This workaround
also makes wireless hotkey work.
