Hi all,
After merging the tip tree, today's linux-next build (powerpc
pseries_le_defconfig) failed to boot like this:

In Restricted CXL Device (RCD) mode a CXL device is exposed as an
RCiEP, but CXL downstream and upstream ports are not enumerated and
not visible in the PCIe hierarchy. Protocol and link errors are sent
to an RCEC.

Thanks for taking another look into this Christophe!
