[anton@samba.org: [PATCH]: Bug in ppc32 ld.so]

If the page is not marked guarded the cpu can instruction prefetch into the
page. Can you guarantee that current and future CPUs will never prefetch
into the icache clean area?

When I mentioned the current behaviour one of the ppc architects warned me
we were asking for trouble.
