Thanks for the feedback. I am not in a rush to get either series into
5.14 so that sounds fine with me. Here is how I am planning to proceed:

1. Send a new series with the cleanups to is_tdp_mmu_root Sean suggested
   in patch 1/8 [1].
2. Send v2 of the TDP MMU Fast Page Fault series without patch 1/8.
3. Send out the memslot lookup optimization series.

Does that sound reasonable to you? Do you have any reservations with
taking (2) before (3)?
