Maybe. I'm just answering your question. :)
Ah yes, I forgot that separate regions for different purposes could
decrease fragmentation.
I would suggest going forward without having multiple regions:
Is having support for multiple regions a bad thing? Frankly,
removing this support will change code from reading context passed
as argument to code reading context from global variable. Nothing
is gained; functionality is lost.
* Remove the registration of specific addresses from the initial patch
set (but keep the patch).
* Add a heuristic plus command-line override to automatically come up
with a reasonable location+size for *one* CMA area in the system.
I'm not arguing those.
