Today xenbus_map_ring_valloc() can return either a negative errno value (-ENOMEM or -EINVAL) or a grant status value. This is a mess as e.g -ENOMEM and GNTST_eagain have the same numeric value. Fix that by turning all grant mapping errors into -ENOENT. This is no problem as all callers of xenbus_map_ring_valloc() only use the return value to print an error message, and in case of mapping errors the grant status value has already been printed by __xenbus_map_ring() before.

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.
