* KVM: s390/mm: cleanup gmap function arguments, variable namesMartin Schwidefsky2014-08-257-70/+72
| | | | | | | | | | | | Make the order of arguments for the gmap calls more consistent, if the gmap pointer is passed it is always the first argument. In addition distinguish between guest address and user address by naming the variables gaddr for a guest address and vmaddr for a user address.

| | | | | | | | | | | The kvm lock protects us against vcpus going away, but they only go away when the virtual machine is shut down. We don't need this mutex here, so let's get rid of it.

* KVM: s390: return -EFAULT if lowcore is not mapped during irq deliveryJens Freimann2014-08-253-25/+24
| | | | | | | | | | | | | | | Currently we just kill the userspace process and exit the thread immediatly without making sure that we don't hold any locks etc. Improve this by making KVM_RUN return -EFAULT if the lowcore is not mapped during interrupt delivery. To achieve this we need to pass the return code of guest memory access routines used in interrupt delivery all the way back to the KVM_RUN ioctl.

* KVM: s390: synchronize more registers with kvm_runDavid Hildenbrand2014-08-252-14/+56
| | | | | | | | | | | | | | | | | | | In order to reduce the number of syscalls when dropping to user space, this patch enables the synchronization of the following "registers" with kvm_run: - ARCH0: CPU timer, clock comparator, TOD programmable register, guest breaking-event register, program parameter - PFAULT: pfault parameters (token, select, compare) The registers are grouped to reduce the overhead when syncing. As this grows the number of sync registers quite a bit, let's move the code synchronizing registers with kvm_run from kvm_arch_vcpu_ioctl_run() into separate helper routines.

At the same time the error handling for brightness_max was modified to do the same, this is wrong, when there is no brightness_max asus-wmi should not register a backlight interface. Note the caller of asus_wmi_backlight_init already special cases -ENODEV, and will not cause the wmi driver regristration to fail because of a -ENODEV return from asus_wmi_backlight_init. https://bugzilla.redhat.com/show_bug.cgi?id=1097436 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
