Now that the 'struct cxl_dpa_partition' array contains both size and
performance information, all paths that iterate over that information
can use a loop rather than hard-code 'ram' and 'pmem' lookups.
Remove, or reduce the scope of the temporary helpers that bridged the
pre-'struct cxl_dpa_partition' state of the code to the post-'struct
cxl_dpa_partition' state.
- to_{ram,pmem}_perf(): scope reduced to just sysfs_emit + is_visible()
helpers
- to_{ram,pmem}_res(): fold into their only users cxl_{ram,pmem}_size()
- cxl_ram_size(): scope reduced to ram_size_show() (Note,
cxl_pmem_size() also used to gate nvdimm registration)
In short, memdev sysfs ABI already made the promise that 0-sized
partitions will show for memdevs, but that can be avoided for future
partitions by using dynamic sysfs group visibility (new relative to when
the partition ABI first shipped upstream).

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.
