The ASPM patches fix a v6.7 regression, so it would be good to fix
that in v6.8.

Mani, if you are OK with them, I can add them to for-linus for v6.8.  

What about the 'required-opps' and 'msi-map-mask' patches?  If they're
important, I can merge them for v6.8, too, but it's late in the cycle
and it's not clear from the commit logs why they shouldn't wait for
v6.9.
