How about this:

struct ioctl_payload {
    int how_many;
    int* numbers;
};

User space sets things up normally, with a valid pointer in 'numbers'.
Kernel space copy_from_user the structure, then copy_from_user the number's
memory...

Can that work? If so, numbers could of course be any data structure we want...
