It turns out this change will make things worse for the (unfortunately common) EL1+64GB+brokenfirmware case.

Because of that I think the Fixes: tag and "(fix 64GB models)" should be dropped from the commit message. (I can also send a v2 with extra info in the commit message if needed)

Unlike the phone SoCs this was copied from, x1e has a 40-bit physical bus.
The upper address space is used to support more than 32GB of memory.

This fixes issues when DMA buffers are allocated outside the 36-bit range.



Applied, thanks!
