      Avoid using variable-length arrays in kernel/sys.c · a84a79e4
      Linus Torvalds authored
      The size is always valid, but variable-length arrays generate worse code
      for no good reason (unless the function happens to be inlined and the
      compiler sees the length for the simple constant it is).
      
      Also, there seems to be some code generation problem on POWER, where
      Henrik Bakken reports that register r28 can get corrupted under some
      subtle circumstances (interrupt happening at the wrong time?).  That all
      indicates some seriously broken compiler issues, but since variable
      length arrays are bad regardless, there's little point in trying to
      chase it down.
      
      "Just don't do that, then".
