This is the second version of providing a base to support device MSI (non
PCI based) and on top of that support for IMS (Interrupt Message Storm)
based devices in a halfways architecture independent way.

After applying this patch series, the dmar_alloc_hwirq() helper doesn't
work anymore during boot. This causes the IOMMU driver to fail to
register the DMA fault handler and abort the IOMMU probe processing.
Is this a known issue?

See replies to patch 15/46 or pull the git tree. It has the issue fixed.

Thanks,
