Add support for clean shutdown of the root partition when running on MSHV hypervisor. v3: - Dropped acpi_sleep handlers as they are not used on mshv - Applied ordering for hv_reboot_notifier - Fixed build issues on i386, arm64 architectures v2: - Addressed review comments from v1. - Moved all sleep state handling methods under CONFIG_ACPI stub - - This fixes build issues on non-x86 architectures.

I don't see any code context or logical dependency on that series, but correct me if I'm wrong. If there's no dependency, can you send a v4 based on Linus' tree or hyperv-next to avoid a merge conflict? Thanks, Easwar (he/him)
