8b14518fad x86, AMD IOMMU: honor iommu=off instead of amd_iommu=off
This patch removes the amd_iommu=off kernel parameter and honors the generic
iommu=off parameter for the same purpose.

999ba417cc x86, AMD IOMMU: flush domain TLB when there is more than one page to flush
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.

ea7b44c8e6 enable bus mastering on i915 at resume time
On 9xx chips, bus mastering needs to be enabled at resume time for much of the
chip to function.  With this patch, vblank interrupts will work as expected
on resume, along with other chip functions.   Fixes kernel bugzilla #10844.
