So then your earlier response was misleading, or at least confusing
me:

"I did not get detail spec either, but linux kernel has remove this page
 0x20110000 already for the same reason, refer to commit:
 a9acc5365dbda29f7be2884efb63771dc24bd815".

"Removed" to me meant removed from the list of bad PFNs. Note
that I didn't look at the commit, I just took your response as
confirming that this particular PFN got added to the list in error.
Now that you say that you actually meant the exact opposite,
we're back at the question why that PFN is in the list in the first
place, considering that none of the spec updates say so.
