Subject: [PATCH 0/7] amd iommu smart tlb flushing

Hi,

this patchset implements a smarter io-tlb flushing strategy for the AMD IOMMU
driver. The old behavior was to flush only a single 4kb entry or the whole
domain io-tlb. This patchset implements book keeping about the ranges of PTEs
changed in the page table and flushes only that ranges when the flush is
actually done.

	Joerg
