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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) iQIcBAABAgAGBQJUwj60AAoJEBF7vIC1phx8iV0QAKq1LZRTmgTLS2fd0oyWKZeN ShWUIUiB+7IUiuogYXZMfqOm61oogxwc95Ti+3tpSWYwkzUWagpS/RJQze7E1HOc 3pHpXwrR01ueUT6uVV4xc/vmVIlQAIl/ScRDDPahlAT2crCleWcKVC9l0zBs/Kut IrfzN9pJcrkmXD178CDP8/VwXsn02ptLQEpidGibGHCd03YVFjp3X0wfwNdQxMbU qOwNYCz3SLfDm5gsybO2DG+aVY3AbM2ZOJt/qLv2j4Phz4XB4t4W9iJnAefSz7JA W4677wbMQpfZlUQYhI78H/Cl9SfWAuLug1xk83O/+lbEiR5u+8zLxB69dkFTiBaH 442OY957T6TQZ/V9d0jDo2XxFrcaU9OONbVLsfBQ56Vwv5cAg9/7zqG8eqH7Nq9R gU3fQesgD4N0Kpa77T9k45TT/hBRnUEtsGixAPT6QYKyE6cK4AJATHKSjMSLbdfj ELbt0p2mVtKhuCcANfEx54U2CxOrg5ElBmPz8hRw0OkXdwpqh1sGKmt0govcHP1I BGSzE9G4mswwI1bQ7cqcyTk/lwL8g3+KQmRJoOcgCveQlnY12X5zGD5DhuPMPiIT VENqbcTzjlxdu+4t7Enml+rXl7ySsewT9L231SSrbLsTQVgCudD1B9m72WLu5ZUT 9/Z6znv6tkeKV5rM9DYE =zLjR -----END PGP SIGNATURE----- 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.
