This patch changes the domain TLB flushing behavior of the driver. When there
is more than one page to flush it flushes the whole domain TLB instead of every
single page. So we send only a single command to the IOMMU in every case which
is faster to execute.

7441e9cb18 x86, AMD IOMMU: disable suspend/resume with IOMMU enabled (for now) 
This patch disables suspend/resume on machines with AMD IOMMU enabled. Real
suspend/resume support for AMD IOMMU is currently being worked on. Until this
is ready it will be disabled to avoid data corruption when the IOMMU is not
properly re-enabled at resume. The patch is based on a similar patch for the
GART driver written by Pavel Machek.

The overall driver merged into tip/master is tested with parallel disk and
network loads and showed no problems in a test running for 3 days.
