I notice that menuconfig is a bit weird after this.

The "General setup" menu offers the "Live Update and Kexec HandOver"
menu but there's nothing in there.  If one sets
DEFERRED_STRUCT_PAGE_INIT then things look normal.

Perhaps we shouldn't be offering "Live Update and Kexec HandOver" at
all if !DEFERRED_STRUCT_PAGE_INIT.
