Currently, when adding memory, we create entries in /sys/firmware/memmap/ as "System RAM". This does not reflect the reality and will lead to kexec-tools to add that memory to the fixed-up initial memmap for a kexec kernel (loaded via kexec_load()). The memory will be considered initial System RAM by the kexec kernel. We should let the kexec kernel decide how to use that memory - just

This is the follow up of [1]: [PATCH v1 0/3] mm/memory_hotplug: Make virtio-mem play nicely with kexec-tools I realized that this is not only helpful for virtio-mem, but also for dax/kmem - it's a fix for that use case (see patch #3) of persistent memory. Also, while testing, I discovered that kexec-tools will *not* add dax/kmem memory (anything not directly under the root when parsing
