If you'd like to tell Intel to stop filing bugs about Intel SDVs that
won't boot via EFI, be my guest. These are systems that have no problem
booting Windows because SetVirtualAddressMap() is called in the Windows
bootloader rather than in the Windows kernel.

No. We don't know where the kernel will map the runtime regions.
