From: Greg KH <gregkh@linuxfoundation.org>

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

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

From: Zhang Rui <rui.zhang@intel.com>

commit 76eb9a30db4bc8fd172f9155247264b5f2686d7b upstream.

Dell Precision M6600 is known to require PCI reboot, so add it to
the reboot blacklist in pci_reboot_dmi_table[].
