IIUC this breaks "normal" bzImage boot, so we should have something like
The resulting kernel will not boot with most x86 boot loaders
such as GRUB or SYSLINUX. Unless you plan to start the kernel
using QEMU or Xen, you probably want to say N here.
and also
depends on !EFI
because even though in principle it would be possible to write a PVH
loader for UEFI, PVH's start info does not support the EFI handover
protocol.
