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. -- []'s Thiago Jung Bauermann IBM Linux Technology Center
