Jon Mason 76fd231717 [PATCH] x86-64: Calgary IOMMU: Fix off by one when calculating register space location 
The purpose of the code being modified is to determine the location
of the calgary chip address space.  This is done by a magical formula
of FE0MB-8MB*OneBasedChassisNumber+1MB*(RioNodeId-ChassisBase) to
find the offset where BIOS puts it.  In this formula,
OneBasedChassisNumber corresponds to the NUMA node, and rionodeid is
always 2 or 3 depending on which chip in the system it is.  The
problem was that we had an off by one error that caused us to account
some busses to the wrong chip and thus give them the wrong address
space.

Fixes RH bugzilla #203971.
