Yep, exactly, the point of making the changes together with the
move was to keep things bisectable.

Oh, right you are. Actually, if I'd change the module name via
Makefile (i.e. ramoops-objs = ram.o), we can get rid of
MODULE_PARAM_PREFIX hack. So, I'd just name the module ramoops.ko
name, but keep the ram.c source file name.

Thanks for the hint.

Fixed, thanks!
