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.
