Changes since v5:
- Use a private parser for cxl_poison events. (Dan)
Previously used the default parser and re-parsed per the cxl-list
needs. Replace that with a private parsing method for cxl_poison.
- Add a private context to support private parsers.
- Add helpers to use with the cxl_poison parser.
- cxl list json: drop nr_records field (Dan)
- cxl list option: replace "poison" w "media-errors" (Dan)
- cxl list json: replace "poison" w "media_errors" (Dan)
- Link to v5:

Begin cover letter:
Add the option to add a memory devices poison list to the cxl-list
json output. Offer the option by memdev and by region. Sample usage:
# cxl list -m mem1 --media-errors
