The need for CMA is highly dependent on the hardware and applications
used. 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.
