The ACPI CEDT.CFMWS indicates a range of possible address where new CXL
regions can appear. Each range is associated with a QTG id (QoS
Throttling Group id). For each range + QTG pair that is not covered by a proximity
domain in the SRAT, Linux creates a new NUMA node. However, the commit
that added the new ranges missed updating the node_possible mask which
causes memory_group_register() to fail. Add the new nodes to the
nodes_possible mask.

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.
