You have the function returning the newly initalized PE here...

... but then you ignore the result here and in the other function you've
modified.
It looks like you're using the result in the next patch though, so I
wonder if you would be better to merge this patch with the next
one. However, as I said before I'll defer to Alexey on decisions about
how to split the patch series if he has a different opinion.
