Fix UUID endianness patch breaks cloud-init on Azure
Status in linux package in Ubuntu:
On Azure, cloud-init relies on the system-uuid as based by SMBIOS a
unique ID for a cloud instance. If this ID ever changes, then cloud-
init will attempt to reprovision the VM.
This recent kernel patch in the Ubuntu kernel corrects the endianness
for some SMBIOS fields, but also has the effect causing cloud-init to
think that the system-uuid has changed:
The impact is that cloud-init attempts to reprovision the VM, often
causing the customer to lose access to their VM.
