This series marks the cxl and cxlflash drivers as obsolete/deprecated, disables them by default, and prints a warning to users on probe. CAPI devices have been out of production for some time, and we're not aware of any remaining users who are likely to want a modern kernel. There's almost certainly some remaining driver bugs and we don't have much hardware available to properly test the drivers any more. This was previously discussed at [0] - I've decided not to try to do anything funny with the Kconfig settings as explored in that thread, as it seems unlikely to have any significant benefit. This series will be followed up with patches to remove the drivers and associated arch code, which I hope will be merged in the following cycle.
