The CXL specification defines a mechanism for namespaces to be comprised of multiple dis-contiguous ranges. Introduce that concept to the legacy NVDIMM namespace implementation with a new nsl_set_nrange() helper, that sets the number of ranges to 1. Once the NVDIMM subsystem supports CXL labels and updates its namespace capacity provisioning for dis-contiguous support nsl_set_nrange() can be updated, but in the meantime CXL label validation requires nrange be non-zero.

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.
