So, how would you like to go about this series?

To help move it forward I applied the first 5 commits to tip:x86/dax, on a
vanilla v4.17-rc5 base, did some minor edits to the changelogs, tested it
superficially (I don't have DAX so this essentially means build tests) and
pushed out the result.

Barring some later generic-x86 regression (unlikely) this looks good to me - feel 
free to cross-pull that branch into your DAX/nvdimm tree.

Or we could apply the remaining changes to -tip too - your call.

Thanks,

	Ingo
