Stephen reported that an htmldocs build hit:
Documentation/ABI/testing/debugfs-cxl:38: ERROR: Unexpected indentation.
It turns out that line was fine but the tool was unhappy about some line
breaks in the table of values to error types.
It turns out that:
make V=1 SPHINXDIRS="admin-guide" htmldocs
...can not be used to get more info about what is behind a documentation
build error. It was only pure luck that reflowing the text resulted in
an error message that seemed a imply a problem later on with line breaks
around the table.

Export CXL helper functions in einj-cxl.c for getting/injecting
available CXL protocol error types to sysfs under kernel/debug/cxl.
The kernel/debug/cxl/einj_types file will print the available CXL
protocol errors in the same format as the available_error_types
file provided by the einj module. The
kernel/debug/cxl/$dport_dev/einj_inject file is functionally the same
as the error_type and error_inject files provided by the EINJ module,
i.e.: writing an error type into $dport_dev/einj_inject will inject
said error type into the CXL dport represented by $dport_dev.

Inject and Clear Poison commands are optionally supported by CXL
memdev devices and are intended for use in debug environments only.
Add debugfs attributes for user access.
Documentation/ABI/testing/debugfs-cxl describes the usage.
