The suggestions during the last set of reviews (my v3 patchset) was to introduce arch specific details like TCR_EL1.TxSZ in the vmcoreinfo and also to wait for the 52-bit changes to make way upstream (as I raised a couple of issues/kernel panic issues) earlier with the 52-bit VA changes from Steve. I plan to send out the v4 patchset later this week (and will Cc you so that you can test the same).
