As I understand, the only concern was the type change for dtb_mem.
This was one of the review comments for my patch
https://lore.kernel.org/lkml/20191204155938.2279686-21-pasha.tatashin@xxxxxxxxxx/
(I believe it was from Marc Zyngier), I add a number of new fields,
and they all should be phys_addr_t, this is why I change dtb_mem to
phys_addr_t to be consistent.
