This series breaks my funky ivb machine with the broken hpd bits: When I
unplug the screen the system never invalidates the edid and so never
notices that it's gone.

Now iirc you've discovered an issue in our hpd irq handler which can cause
lost hpd bits, but that patch isn't in this series. And iirc I asked you
to resend everything since that hw fix also wasn't in the last series. And
I can't find it any more. Did I just dream about this other patch to fix
hpd on big core?

Thanks, Daniel
