Now that we're applying the IOMMU API reserved regions to our IOVA domains, we shouldn't need to privately special-case PCI windows, or indeed anything else which isn't specific to our iommu-dma layer. However, since those aren't IOMMU-specific either, rather than start duplicating code into IOMMU drivers let's transform the existing function into an iommu_get_resv_regions() helper that they can share.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
