Hi,
in order to implement interrupt remapping using the AMD IOMMU I did some
refactoring of the current Intel-specific interrupt remapping code. The
result is posted for comments in this patch-set.
The patch-set basically removes the Intel-specific calls from the X86
apic and io-apic code and
The operation for releasing a remapping entry is iommu
specific too.

Add routine to invalidate the IOMMU cache for interupt
translations. Also include the IRTE caches when flushing all
IOMMU caches.

Add the routine to setup interrupt remapping for ioapic
interrupts. Also add a routine to change the affinity of an
irq and to free an irq allocation for interrupt remapping.
The last two functions will also be used for MSI interrupts.

Do not deinitialize the AMD IOMMU driver completly when
interrupt remapping is already in use but the initialization
of the DMA layer fails for some reason. Make sure the IOMMU
can still be used to remap interrupts.

The IVRS table usually includes the IOMMU device. But the
IOMMU does never translate itself, so make sure the IOMMU
driver knows this.

The irq remapping tables for the AMD IOMMU need to be
aligned on a 128 byte boundary. Create a seperate slab-cache
to guarantee this alignment.

Instead of taking as-lock before calling alloc_pdir() and
releasing it in that function to allocate memory, just take
the lock only

Hmm, tried it here, At least pci_request_acs() still gets called. How do
