Subject: [PATCH] [1/50] x86: Make Dell Latitude E6420 use reboot=pci

2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: H. Peter Anvin <hpa@...or.com>

[ upstream commit a536877e77f73ea22d12d94a019fedd9671b6acd ]

Yet another variant of the Dell Latitude series which requires
reboot=pci.

>From the E5420 bug report by Daniel J Blueman:

> The E6420 is affected also (same platform, different casing and
> features), which provides an external confirmation of the issue; I can
> submit a patch for that later or include it if you prefer:
