Sigh, I tried.
Zi Yan, we're going to need to find a fix for this. Rapidly, please.

Hi Andrew,
Why cannot we use __pmd(0) instead? My sparc32 fix is in 4.13 now.
commit is 9157259d16a8ee8116a98d32f29b797689327e8d.
It should be OK to use __pmd(0). Is there any other arch not having __pmd()?
Thanks.

I didn't know that. So we should be OK now. Thanks.
