This is utterly impractical without support from the x86 maintainers. I upstream a *lot* of patchsets which alter x86. I looked once. 5% of those patches had an Acked-by or Reviewed-by from an x86 maintainer. I cc you guys until I'm blue in the face and it's always crickets. I simply cannot permit MM or kexec progress to be blocked by the unresponsiveness of the x86 team. It's very regrettable but it's almost always the case that I just have to proceed without your assistance. This particular patchset is a kexec thing so I added it for testing because I look after kexec. I'll drop it and shall trust you to handle Coiby's contribution in an appropriate fashion.
