Subject: [PATCH 00/24] x86/mm: Add KAISER support
Sending this out for another round of review.
These are the main KAISER patches, on top of the preparatory series I just sent.
This includes KAISER support plus enhancements on top, all the latest code.
( All review feedback so far is incorporated - if anything is missing please
let me know. )
Thanks,
Ingo
