Driver core: add dev_archdata to struct device Add arch specific dev_archdata to struct device Adds an arch specific struct dev_arch to struct device. This enables architecture to add specific fields to every device in the system, like DMA operation pointers, NUMA node ID, firmware specific data, etc...

ACPI: Change ACPI to use dev_archdata instead of firmware_data Change ACPI to use dev_archdata instead of firmware_data This patch changes ACPI to use the new dev_archdata on i386, x86_64 and ia64 (is there any other arch using ACPI ?) to store it's acpi_handle. It also removes the firmware_data field from struct device as this was the only user.

[IA64] Add Variable Page Size and IA64 Support in Intel IOMMU The patch contains Intel IOMMU IA64 specific code. It defines new machvec dig_vtd, hooks for IOMMU, DMAR table detection, cache line flush function, etc. For a generic kernel with CONFIG_DMAR=y, if Intel IOMMU is detected, dig_vtd is used for machinve vector. Otherwise, kernel falls back to dig machine vector. Kernel parameter "machvec=dig" or "intel_iommu=off" can be used to force kernel to boot dig machine vector.
