I am working on the changes in the vmcoreinfo after the 52-bit VA
changes from Steve were accepted in Linux 5.4-rc1 ("Support for 52-bit
virtual addressing in kernel space").
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).
Thanks,
Bhupesh
