Yes, please disable CONFIG_ARCH_HIBERATION_POSSIBLE and
CONFIG_ARCH_SUSPEND_POSSIBLE and the obligatory dependencies. We don't
rely on these guest cooperation to pause or suspend a VM.

Title:
  [Hyper-V] Disable CONFIG_HOTPLUG_CPU in linux-azure

Status in linux-azure package in Ubuntu:
  New
Status in linux-azure source package in Bionic:
  In Progress

Bug description:
  While Hyper-V may present all potential CPUs via ACPI MADT, CPU
  add/remove is not supported. This results in kernel data structures
  created for the largest potential size based on the number of CPUs
  when those CPUs will never be added during the time the guest is up
  (it can certainly be resized when it's down and deallocated). Please
  disable CONFIG_HOTPLUG_CPU in linux-azure.
