There are other parties who would like to use these flags! Yes, I know that. On the other hand, we have terminally broken CPU hotplug code in the kernel that I'd like to get fixed _first_. > I think my patch localizes the suspend material properly.

PageNosave should be visible to the architectures so that they can mark nosave pages for the suspend. > What is the problem with the patch? PageNosaveFree is only needed at the suspend time, so we need not allocate it in advance. > How long will it take you to remove the flags on your own? I can't promise anything, because that also depends on people who work on the CPU hotplug, workqueues etc. and these things are hard. I'll do that as soon as I can.
