	     The problem occurs due to prefetch across a page boundary
	     where stale instructions can be fetched from the next
	     page, and the mechanism for flushing these bad
	     instructions fails under certain circumstances.  The
	     unconditional branches:
	     1) Branch: b, bl, ba, bla,
	     2) Branch Conditional: bc, bca, bcl, bcla,
	     3) Branch Conditional to Link Register: bclr, bclrl,
	     where (2) and (3) have BO=0x14 making them unconditional,
	     prevent the bad prefetch because the prefetch itself is
	     affected by these instructions.  This happens even if the
	     instruction is not executed.

	     A bctr example:
	     .
	     .	lis 9,new_page@ha
	     .	addi 9,9,new_page@l
	     .	mtctr 9
	     .	bctr
	     .	nop
	     .	nop
	     . new_page:
	     .
	     The bctr is not predicted taken due to ctr not being
	     ready, so prefetch continues on past the bctr into the
	     new page which might have stale instructions.  If they
	     fail to be flushed, then they will be executed after the
	     bctr executes.  Either of the following modifications
	     prevent the bad prefetch from happening in the first
	     place:
	     .
	     .	lis 9,new_page@ha	 lis 9,new_page@ha
	     .	addi 9,9,new_page@l	 addi 9,9,new_page@l
	     .	mtctr 9			 mtctr 9
	     .	bctr			 bctr
