2008-07-04x86, AMD IOMMU: honor iommu=off instead of amd_iommu=offJoerg Roedel
This patch removes the amd_iommu=off kernel parameter and honors the generic iommu=off parameter for the same purpose.

2008-07-04x86, AMD IOMMU: flush domain TLB when there is more than one page to flushJoerg Roedel
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.

2008-07-04x86, AMD IOMMU: remove unnecessary set_bit_stringJoerg Roedel
The set_bit_string call in the address allocator is not necessary because its already called in iommu_area_alloc().

2008-06-30x86, AMD IOMMU: disable suspend/resume with IOMMU enabled (for now)Joerg Roedel
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.
