I'm puzzled by the use of "a generic piece of memory" to store "persistent"
things (Perhaps this is made clear in the 17 parts of the patch? I haven't
read them yet). On x86 f/w typically clears all of memory on reset ... so
you only get persistence if you use kexec to get from the old kernel to
the new one.
