Subject: [PATCH v3 0/2] Add support for clean shutdown with MSHV

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.

Praveen K Paladugu (2):
  hyperv: Add definitions for MSHV sleep state configuration
  hyperv: Enable clean shutdown for root partition with MSHV
