The one concept that I'm missing (but that I can easily produce a follow-up
patch for, as I had this in my c_p_a() changes) is the tracking and adjusting
of the reference protection for a large page range that got fully converted
to another type (namely relevant for .rodata if it exceeds 2/4 Mb), allowing
to use a large page mapping in this case even for non-default mappings.

Apart from the other comments, the whole series
