2.6.34-stable review patch. If anyone has any objections, please let us know.

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

From: Borislav Petkov <borislav.petkov(a)amd.com>

commit 9975a5f22a4fcc8d08035c65439900a983f891ad upstream.

The correct check is to verify whether in high range we're below 4GB
and not to extract the DctSelBaseAddr again. See "2.8.5 Routing DRAM
Requests" in the F10h BKDG.
