Since it was pushed only for 15 minutes or so, and the fix is two lines: diff --git a/virt/kvm/kvm_main.c b/virt/kvm/kvm_main.c index 30425ce6a4a4..848af90b8091 100644 --- a/virt/kvm/kvm_main.c +++ b/virt/kvm/kvm_main.c @@ -1669,7 +1669,7 @@ int kvm_read_guest_atomic(struct kvm *kvm, gpa_t gpa, void *data, struct kvm_memory_slot *slot = gfn_to_memslot(kvm, gfn); int offset = offset_in_page(gpa); - return __kvm_read_guest_atomic(slot, gpa, data, offset, len); + return __kvm_read_guest_atomic(slot, gfn, data, offset, len); } EXPORT_SYMBOL_GPL(kvm_read_guest_atomic); @@ -1680,7 +1680,7 @@ int kvm_vcpu_read_guest_atomic(struct kvm_vcpu *vcpu, gpa_t gpa, struct kvm_memory_slot *slot = kvm_vcpu_gfn_to_memslot(vcpu, gfn); int offset = offset_in_page(gpa); - return __kvm_read_guest_atomic(slot, gpa, data, offset, len); + return __kvm_read_guest_atomic(slot, gfn, data, offset, len); } EXPORT_SYMBOL_GPL(kvm_vcpu_read_guest_atomic); I just force-pushed kvm/next. The patch is good, but I prefer to do minimal changes before fleeing on holiday.
