Hi,
Please find the following patches which help support
Non-Transparent-Bridge (NTB) devices on AMD platforms with the IOMMU
enabled.
The first patch implements dma_map_resource() correctly with the AMD
IOMMU. This is required for correct functioning of ntb_transport which
uses that interface.
From: Kit Chow
Currently the Intel IOMMU uses the default dma_[un]map_resource()
implementations does nothing and simply returns the physical address
unmodified.
However, this doesn't create the IOVA entries necessary for addresses
mapped this way to work when the IOMMU is enabled. Thus, when
Non-Transparent Bridge (NTB) devices (among others) may have many DMA
aliases seeing the hardware will send requests with different device ids
depending on their origin across the bridged hardware.
See commit ad281ecf1c7d ("PCI: Add DMA alias quirk for Microsemi Switchtec
NTB") for more

As platform_get_irq() now prints an error when the interrupt does not
exist, counting interrupts by looping until failure causes the printing
of scary messages like:
rk_iommu ff924000.iommu: IRQ index 1 not found
rk_iommu ff914000.iommu: IRQ index 1 not found
rk_iommu ff903f00.iommu: IRQ index

Applied, thanks. Note that it will not show up in linux-next before
