Define an interface that the NX drivers can use to find the physical paste address of a send window. This interface is expected to be used with the mmap() operation of the NX driver's device. i.e the user space process can use driver's mmap() operation to map the send window's paste address into their address space and then use copy and paste instructions to submit the CRBs to the NX engine. Note that kernel drivers will use vas_paste_crb() directly and don't need this interface.

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.
