The PSCI v1.3 spec (https://developer.arm.com/documentation/den0022) adds support for a SYSTEM_OFF2 function enabling a HIBERNATE_OFF state which is analogous to ACPI S4. This will allow hosting environments to determine that a guest is hibernated rather than just powered off, and ensure that they preserve the virtual environment appropriately to allow the guest to resume safely (or bump the hardware_signature in the FACS to trigger a clean reboot instead).

I grabbed the KVM portions of this series, as they look ready to go. Happy to take the last one through kvmarm tree w/ acks, and can toss it on top.
Applied to kvmarm/next, thanks!
