I want to be able to call the runtime services in the kexec kernel.
Which means, the kexec kernel would simply map the runtime code/data
regions 1:1 and then use the physical addresses to call the runtime
services.
Question is: would that work even if SetVirtualAddressMap has already
run in the original kernel and with virtual addresses?
