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.

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.

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 .

...
The kvm_* structs are obsoleted by the pvclock_* ones.
Now all users have been switched over and the old structs
can be dropped.
