x86: Fix ASM_X86__ header guards Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

iommu: Rename the DMAR and INTR_REMAP config options Change the CONFIG_DMAR to CONFIG_INTEL_IOMMU to be consistent with the other IOMMU options. Rename the CONFIG_INTR_REMAP to CONFIG_IRQ_REMAP to match the irq subsystem name. And define the CONFIG_DMAR_TABLE for the common ACPI DMAR routines shared by both CONFIG_INTEL_IOMMU and CONFIG_IRQ_REMAP.

intel-iommu: fix for IOMMU early crash pci_dev's->sysdata is highly overloaded and currently IOMMU is broken due to IOMMU code depending on this field. This patch introduces new field in pci_dev's dev.archdata struct to hold IOMMU specific per device IOMMU private data.

x86/PCI: Allow DMA ops specific to a PCI domain The Intel Volume Management Device (VMD) is a PCIe endpoint that acts as a host bridge to another PCI domain. When devices below the VMD perform DMA, the VMD replaces their DMA source IDs with its own source ID. Therefore, those devices require special DMA ops. Add interfaces to allow the VMD driver to set up dma_ops for the devices below it.

Driver Core: Add platform device arch data V3 Allow architecture specific data in struct platform_device V3. With this patch struct pdev_archdata is added to struct platform_device, similar to struct dev_archdata in found in struct device. Useful for architecture code that needs to keep extra data associated with each platform device. Struct pdev_archdata is different from dev.platform_data, the convention is that dev.platform_data points to driver-specific data. It may or may not be required by the driver. The format of this depends on driver but is the same across architectures. The structure pdev_archdata is a place for architecture specific data. This data is handled by architecture specific code (for example runtime PM), and since it is architecture specific it should _never_ be touched by device driver code. Exactly like struct dev_archdata but for platform devices.
