I am not sure why you are advocating that path.

My thinking is that what should be done to have some sense of history
is that the patch in GRUB to not rely on kernel internals should be done.
Then that git commit of that tree should be mentioned in this kernel patch.

This way one can nicely follow the trail of changes and see what the
interdependencies are (or rather that they have been removed).

I wouldn't want GRUB2 to have regressions and stop generating the proper
menu options. That smells of userspace regressions and I am not too
keen to have Linus point this out to me.

Once that is done we can follow up on this patch and perhaps also
nicely convience the initial author of this patch to look at removing the
CONFIG_XEN_DOM0 and replacing them with the two other CONFIG options
that Jan and me have been discussing.
