How about just leaving it alone?  A void * is
perfectly valid as rheap could be used to manage
any address space.  It isn't a bug, you are reducing
it's capability (by taking it's object management
outside of the kernel virtual space), and you are
introducing concerns for error conditions of
current users.

Thanks.
