I don't really think a comprehensive address check is a good idea. It would take too long to scan the mmap list for each address passed in to a system call. Better just not to do the check, or limit it to some reasonable upper bound as we do now. For FRV, the lower limit can be as low as 1 and the upper limit (if doing XIP) 0xffffffff.
