Hi Michael,

I think this is ready to go as a first version. There are a couple of
future work items related to kexec/kdump:
- Teach kexec-tools/kexec_file_load() to not place the kexec
  kernel/initrd onto virtio-mem added memory.
- Teach kexec-tools/kdump to consider a bigger number of memory
  resources for dumping.

In general, as virtio-mem adds a lot of memory resources, we might want
to tweak performance in that area as well. Future stuff.

So I suggest queuing this. If you need a resend, please let me know.

Cheers!

I'll queue it for merge after the release. If possible please ping me
after the release to help make sure it didn't get dropped.

If we could get this into 5.8, that would be great (IOW, have it in
-next for a while before the 5.8 merge window opens).

Thanks!
