[ Upstream commit 11270e526276ffad4c4237acb393da82a3287487 ] Both generic node and HMAT handling code have been using magic numbers to indicate access classes for 'struct access_coordinate'. Introduce enums to enumerate the access0 and access1 classes shared by the two subsystems. Update the function parameters and callers as appropriate to utilize the new enum. Access0 is named to ACCESS_COORDINATE_LOCAL in order to indicate that the access class is for 'struct access_coordinate' between a target node and the nearest initiator node. Access1 is named to ACCESS_COORDINATE_CPU in order to indicate that the access class is for 'struct access_coordinate' between a target node and the nearest CPU node.

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.
