IMHO the right place for such code is in drivers/misc instead of tools/cma.

This patch contains a kernel module source code so it should be put with other kernel
modules. tools/ directory is aimed to contain user space code useful for developing and
testing Linux kernel.

it is not a real driver at all.

Yeah, I feel like it's better placed in tools/ not to pollute other directories with
drivers that are of no use to regular users. I don't have strong feelings about it
though, so I'm fine either way.
