Azure is planning to have VM sizes that boot from NVMe storage, so the NVMe
drivers need to be in the kernel image itself, or if the NVMe driver is built
as a module, the module needs to be included in the initramfs file. Setting CONFIG_HYPERV=Y, CONFIG_PCI_HYPERV=Y and CONFIG_BLK_DEV_NVME=Y does the former, but the latter is acceptable.

Two out of the three configs are set to Y, but we would need CONFIG_PCI_HYPERV set to Y to build the NVMe driver into the kernel. Otherwise, we would need an initrd to all booting from NVMe

Microsoft would like to request either of these changes in all the supported releases.
