-         Support for hardware IOMMUs in IBM's xSeries x366 and x460
-         systems. Needed to run systems with more than 3GB of memory
-         properly with 32-bit PCI devices that do not support DAC
-         (Double Address Cycle). Calgary also supports bus level
-         isolation, where all DMAs pass through the IOMMU.  This
-         prevents them from going anywhere except their intended
-         destination. This catches hard-to-find kernel bugs and
-         mis-behaving drivers and devices that do not use the DMA-API
-         properly to set up their DMA buffers.  The IOMMU can be
-         turned off at boot time with the iommu=off parameter.
-         Normally the kernel will make the right choice by itself.

-         Calgary anyway, pass 'iommu=calgary' on the kernel command line.
