Bug description:
  Please take these patches to our Hyper-V VMBus driver to enable kernel
  crash notification:

  Drivers: hv: vmbus: Add support for VMBus panic notifier handler
  https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/drivers/hv?id=96c1d0581d00f7abe033350edb021a9d947d8d81

  Drivers: hv: vmbus: Correcting truncation error for constant HV_CRASH_CTL_CRASH_NOTIFY
  https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/drivers/hv?id=5ef5b6927f14f29cacd78fa1fb861661a5367f13

  
  In the event of a kernel panic, VMBus driver supports sending five 64-bit values to be recorded in the log.  On Hyper-V this is recorded in the event log, and on Azure we can use this data to better detect failures like this in the guest VM and surface that as part of our diagnostics information.
