Merge tag 'kvm-s390-next-20150122' of git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux into kvm-next
KVM: s390: fixes and features for kvm/next (3.20) 1. Generic - sparse warning (make function static) - optimize locking - bugfixes for interrupt injection - fix MVPG addressing modes 2. hrtimer/wakeup fun A recent change can cause KVM hangs if adjtime is used in the host. The hrtimer might wake up too early or too late. Too early is fatal as vcpu_block will see that the wakeup condition is not met and sleep again. This CPU might never wake up again. This series addresses this problem. adjclock slowing down the host clock will result in too late wakeups. This will require more work. In addition to that we also change the hrtimer from REALTIME to MONOTONIC to avoid similar problems with timedatectl set-time. 3. sigp rework We will move all "slow" sigps to QEMU (protected with a capability that can be enabled) to avoid several races between concurrent SIGP orders. 4. Optimize the shadow page table Provide an interface to announce the maximum guest size. The kernel will use that to make the pagetable 2,3,4 (or theoretically) 5 levels. 5. Provide an interface to set the guest TOD We now use two vm attributes instead of two oneregs, as oneregs are vcpu ioctl and we don't want to call them from other threads. 6. Protected key functions The real HMC allows to enable/disable protected key CPACF functions. Lets provide an implementation + an interface for QEMU to activate this the protected key instructions.
