Dave Jiang f4d027921c cxl: Fix match_region_by_range() to use region_res_match_cxl_range()
match_region_by_range() is not using the helper function that also takes
extended linear cache size into account when comparing regions. This
causes a x2 region to show up as 2 partial incomplete regions rather
than a single CXL region with extended linear cache support. Replace
the open coded compare logic with the proper helper function for
comparison. User visible impact is that when 'cxl list' is issued,
no activa CXL region(s) are shown. There may be multiple idle regions
present. No actual active CXL region is present in the kernel.

[dj: Fix stable address]

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 reStructuredText 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.
