I've sent that series of patches for review. Assuming you like it,
please pull those patches and a couple of other fixes -- one cosmetic
and one serious crash fix (another BIOS workaround, in fact), from

git://git.infradead.org/~dwmw2/iommu-2.6.32.git

David Woodhouse (5):
      intel-iommu: Yet another BIOS workaround: Isoch DMAR unit with no TLB space
      Rename pci_init() to pci_apply_final_quirks(), move it to quirks.c
      Mark pci_apply_final_quirks() __init rather than __devinit
      Run pci_apply_final_quirks() sooner.
      x86: Move pci_iommu_init to rootfs_initcall()

Roland Dreier (2):
      intel-iommu: Make "Unknown DMAR structure" message more informative
      intel-iommu: Decode (and ignore) RHSA entries
