I am going to give up, I do not understand the changes in -mm ;)

But I think we have other problems which should be fixed first.
Note that each fix has the "this is _not_ enough" comment. I was
going to _try_ to do something more complete later, but since we
are going to add more hacks^W subtle changes... lets fix the obvious
bugs first.

Add Linus. Hopefully the changes are simple enough. But once again,
we need more.

Oleg.
