No, we need to get those baseline patches in, there is no ability to
detect an sync point for "all CXL devices present at boot have had a
chance to probe" without the synchronous registration changes.

I will push a branch with finished patches rather than RFC quality, and
you can build from there. The order of the series should be Sync Probe
changes, DAX HMEM, protocol error series, Type-2.
