Hi All,

On my Thinkpad T14S OLED with 64GB, with this patch applied, I am unable to boot
the laptop anymore. It doesn't matter whether I have mem=30GB, nor if I set
CONFIG_ARM64_VA_BITS_39, or not limiting the ram - shortly after loading the
device tree, the laptop just resets.

I have tried over 20 boots with it applied, as well as trying both booting a
working kernel, and then rebooting as well as cold boots.
