You need to expand that comment with text from Jan & Keir's patch:
Andrew will want to know just what this bug was. The patch looks
good to me, except for the unnecessary do { } while (0) in the
definition of pte_clear: ah, you're only copying what was already
there, can't blame you for that, let's not worry about it.
I agree: the patch comment is rather brief, but the patch itself looks
good. I suppose switching PAE's set_pte() from smp_wmb() to wmb() would
logically belong in a separate patch.
