We're looking at supporting up to a 2TB aarch64 system utilizing Rust Hypervisor Firmware. If this limit is greater than what RHF wants to support I can lower it to something more reasonable and then support 2TB in our own fork, but this appears to be the main issue that we were running into in #298. |

Bumping the possible page table range for aarch64 from 128G to 2TB to support larger systems. Without this increase we can't virtualize system memory beyond 128G for ARM CPUs.
