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. 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)
