This small series fixes two bugs in s390 KVM. One is small and trivial, the other is pretty bad. * The wrong type of flag was being passed to vcpu_dat_fault_handler(); it expects a FOLL_* flag, but a FAULT_FLAG_* was passed instead. * Due to incorrect usage of mmu_notifier_register(), in some rare cases when running a secure guest, the struct mm for the userspace process would get freed too early and cause a use-after-free.
