Subject[ 01/13] x86/reboot: Add quirk to make Dell C6100 use reboot=pci automatically
Date
3.0-stable review patch.  If anyone has any objections, please let me know.

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

From: Masoud Sharbiani <msharbiani@twitter.com>

commit 4f0acd31c31f03ba42494c8baf6c0465150e2621 upstream.

Dell PowerEdge C6100 machines fail to completely reboot about 20% of the time.
