*	xen/swiotlb: Use the swiotlb_late_init_with_tbl to init Xen-SWIOTLB late ↵	Konrad Rzeszutek Wilk	2012-09-17	1	-0/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	when PV PCI is used. With this patch we provide the functionality to initialize the Xen-SWIOTLB late in the bootup cycle - specifically for Xen PCI-frontend. We still will work if the user had supplied 'iommu=soft' on the Linux command line. Note: We cannot depend on after_bootmem to automatically determine whether this is early or not. This is because when PCI IOMMUs are initialized it is after after_bootmem but before a lot of "other" subsystems are initialized.

*	pci-swiotlb-xen: Add glue code to setup dma_ops utilizing xen_swiotlb_*	Konrad Rzeszutek Wilk	2010-07-27	1	-0/+14
	functions. We add the glue code that sets up a dma_ops structure with the xen_swiotlb_* functions. The code turns on xen_swiotlb flag when it detects it is running under Xen and it is either in privileged mode or the iommu=soft flag was passed in. It also disables the bare-metal SWIOTLB if the Xen-SWIOTLB has been enabled. Note: The Xen-SWIOTLB is only built when CONFIG_XEN is enabled.
