This function will be called before the PCI subsystem is initialized. Therefore dev_name doen't work and IOMMU information can't be printed to the klog as before. Move the code to print that information to a later point where PCI initializtion has already happened. Signed-off-by: Joerg Roedel

[PATCH 16/27] iommu/amd: Split device table initialization into irq and dma part

When the IOMMU is enabled very early (as with irq-remapping) some devices are still in BIOS hand. When dma is blocked early this can cause lots of IO_PAGE_FAULTs. So delay the DMA initialization and do it right before the dma_ops are initialized. To be secure, block all interrupts by default when

[PATCH 11/27] iommu/amd: Convert iommu initialization to state machine
