Hi Dan,

That is true.
Previous version of this patchet was based on yours (hmm-refactor),
but then I decided to not base it here due to lack of feedback.
But if devm_memremap_pages() is going to be the main/common function,
I am totally fine to put the memory-hotplug specific there.

Great, then I will wait for your new patchset, and then I will base
this one on that.

Thanks
