2012-01-23	iommu/amd: Add invalidate-context call-back	Joerg Roedel
	This call-back is invoked when the task that is bound to a pasid is about to exit. The driver can use it to shutdown all context related to that context in a safe way. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-01-23	iommu/amd: Add invalid_ppr callback	Joerg Roedel
	This callback can be used to change the PRI response code sent to a device when a PPR fault fails. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-01-23	iommu/amd: Implement notifiers for IOMMUv2	Joerg Roedel
	Since pages are not pinned anymore we need notifications when the VMM changes the page-tables. Use mmu_notifiers for that. Also use the task_exit notifier from the profiling subsystem to shutdown all contexts related to this task. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-01-23	iommu/amd: Implement IO page-fault handler	Joerg Roedel
	Register the notifier for PPR faults and handle them as necessary. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-01-23	iommu/amd: Add routines to bind/unbind a pasid	Joerg Roedel
	This patch adds routines to bind a specific process address-space to a given PASID. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-01-23	iommu/amd: Implement device aquisition code for IOMMUv2	Joerg Roedel
	This patch adds the amd_iommu_init_device() and amd_iommu_free_device() functions which make a device and the IOMMU ready for IOMMUv2 usage. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-01-23	iommu/amd: Add driver stub for AMD IOMMUv2 support	Joerg Roedel
	Add a Kconfig option for the optional driver. Since it is optional it can be compiled as a module and will only be loaded when required by another driver. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
