[PATCH v10 02/12] iommu/amd: add several helper functions

Move single iommu enabling codes into a wrapper function early_enable_iommu(). This can make later kdump change easier. And also add iommu_disable_command_buffer and iommu_disable_event_buffer for later usage. Signed-off-by: Baoquan He --- drivers/iommu/amd_iommu_init.c | 42
