this patch-set contains some cleanups and patches for the
AMD IOMM driver. The most important part is a workaround
that can be used to get interrupt remapping working even the
the IVRS table provided by the BIOS is broken.


Joerg Roedel (9):
iommu/amd: Remove map_sg_no_iommu()
iommu/amd: Use AMD specific data structure for irq remapping
iommu/amd: Properly initialize irq-table lock
iommu/amd: Move add_special_device() to __init
iommu/amd: Extend IVRS special device data structure
iommu/amd: Add early maps for ioapic and hpet
iommu/amd: Add ioapic and hpet ivrs override
iommu/amd: Don't report firmware bugs with cmd-line ivrs overrides
iommu/amd: Document ivrs_ioapic and ivrs_hpet parameters
