This is the first argument to the mmap syscall isn't it? If the address is 0, i.e. not specified, then MMAP returns an address? This could be clarified. But either way, why do we only use the fixed addresses? And is there any value in having this boolean here? Do we need it, or is it clearer to just get rid of it if we only use the fixed addresses anyway?
