In order to support PCI P2PDMA mappings with dma-iommu, explicitly skip any segments marked with sg_dma_mark_bus_address() in __iommu_map_sg(). These segments should not be mapped into the IOVA and will be handled separately in as subsequent patch for dma-iommu.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
