    kernel - Fix ktrace's handling of system call return values
    
    * Distinguish between int and long returns, properly recording
      long returns (e.g. lseek(), mmap(), read(), write(), etc).
      kdump will then display the correct return value instead of a truncated
      return value for the affected system calls.
    
    * Involves including a return value type width in the sysent and adjusting
      the generator to calculate it.
