Again, this description is wrong for PowerPC. See messages from myself and
Michael Ellerman:
https://lists.infradead.org/pipermail/kexec/2016-June/016250.html
https://lists.infradead.org/pipermail/kexec/2016-June/016253.html
IMHO, it would be simpler if ARM used linux,usable-memory in the same way
that PowerPC does, for consistency.
