[PATCH] remove antiquated comment

  This comment, describing how to optimize for gcc-2.2.2, is so outdated
  it should be removed. It's also quite doubtful it should ever have been
  placed in this file at all (perhaps something under Documentation/ ?).
  This patch removes it.

- * Free_page() adds the page to the free lists. This is optimized for
- * fast normal cases (no error jumps taken normally).
- *
- * The way to optimize jumps for gcc-2.2.2 is to:
- *  - select the "normal" case and put it inside the if () { XXX }
- *  - no else-statements if you can avoid them
- *
- * With the above two rules, you get a straight-line execution path
- * for the normal case, giving better asm-code.
