So I don't think we can set a default which will please everyone. You can always override the built-in default size using the cma parameter on the kernel command line. That said, it seems reasonable to raise the default - when it is larger than needed, the pages not allocated to the drivers that need it can still be allocated to user processes, just not for other in-kernel purposes.
