    AMD64 - Refactor uio_resid and size_t assumptions.
    
    * uio_resid changed from int to size_t (size_t == unsigned long equivalent).
    
    * size_t assumptions in most kernel code has been refactored to operate in a
      64 bit environment.
    
    * In addition, the 2G limitation for VM related system calls such as mmap()
      has been removed in 32 bit environments.  Note however that because
      read() and write() return ssize_t, these functions are still limited
      to a 2G byte count in 32 bit environments.
