No, I'm not, it's you saying that your nopud patch does not have any
fix for the warnings, even though I had fixes posted for months. The
same fix that's in my LPAE series was sent to you to include with your
patch but instead you kept saying (even twice in the past week) that
those warning had no fix. From that, I understand that you really
don't consider my patch a proper fix for the compiler warnings.

I haven't changed anything in my LPAE branch, just posted an
alternative fix-up for the nopud patch. Please _state_ clearly whether
you consider my original (in the LPAE series) fixup valid or not. If
yes, I'm happy that I don't have to rework anything.

Yes, that's fine with me, I already talked to Will about this earlier
today but wanted to get your reply first.
