1. Allow to disable gisa 2. protected virtual machines Protected VMs (PVM) are KVM VMs, where KVM can't access the VM's state like guest memory and guest registers anymore. Instead the PVMs are mostly managed by a new entity called Ultravisor (UV), which provides an API, so KVM and the PV can request management actions. PVMs are encrypted at rest and protected from hypervisor access while running. They switch from a normal operation into protected mode, so we can still use the standard boot process to load a encrypted blob and then move it into protected mode. Rebooting is only possible by passing through the unprotected/normal mode and switching to protected again. One mm related patch will go via Andrews mm tree ( mm/gup/writeback: add callbacks for inaccessible pages) -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABAgAGBQJeZf9tAAoJEBF7vIC1phx89J0P/iv3wCoMNDqAttnHa/UQFF04 njUadNYkAADDrsabIEOs9O+BE1/4BVspnIunE4+xw76p5M/7/g5eIhXWcLudhlnL +XtvuEwz/2ffA9JWAAYNKB7cGqBM9BCC+iYzAF9ah6sPLmlDCoF+hRe0g+0tXSON cklUJFril9bOcxd/MxrzFLcmipbxT/Z4/10eBY+FHcm6SQGOKAtJH0xL7X3PfPI5 L/6ZhML9exsj1Iplkrl8BomMRoYOrvfq/jMaZp9SwmfXaOKYmNU3a19MhzfZ593h bfR92H8kZRy/TpBd7EnpxYGQ/n53HkUhFMhtqkkkeHW1rCo8ccwC4VfnXb+KqQp+ nJ8KieWG+OlKKFDuZPl5Gq+jQqjJfzchbyMTYnBNe+GPT5zg76tJXmQyDn5X9p3R mfg+9ZEeEonMu7px93Ht1gLdPiC2gjRckjuBDPqMGEhG2z2SQ/MLri+WnproIQRa TcE7rZBtuyrGFTq4M4dEcsUW02xnOaav6H57kkl8EwqYwgDHlqoUbt0AvLFyW07a RlH7drmhKDwTJkcOhOLeLNM8Un6NvnsLZ8Lbcr9rRf9Z9Lpc+zW88BSwJ7MM/GH8 FEQM8Omnn8KAJTENpIm3bHHyvsi0kJEhl+c3Ila3QnYzXZbJ3ZDaJZngMAbUUnVl YNeFyyALzOgVVBx4kvTm =x6Hn -----END PGP SIGNATURE----- Merge tag 'kvm-s390-next-5.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux into HEAD KVM: s390: Features and Enhancements for 5.7 part1 1.
