Linus Torvalds fd7e9a8834 4.11 is going to be a relatively large release for KVM, with a little over ... 200 commits and noteworthy changes for most architectures. * ARM: - GICv3 save/restore - cache flushing fixes - working MSI injection for GICv3 ITS - physical timer emulation * MIPS: - various improvements under the hood - support for SMP guests - a large rewrite of MMU emulation. KVM MIPS can now use MMU notifiers to support copy-on-write, KSM, idle page tracking, swapping, ballooning and everything else. KVM_CAP_READONLY_MEM is also supported, so that writes to some memory regions can be treated as MMIO. The new MMU also paves the way for hardware virtualization support. * PPC: - support for POWER9 using the radix-tree MMU for host and guest - resizable hashed page table - bugfixes. * s390: expose more features to the guest - more SIMD extensions - instruction execution protection - ESOP2 * x86: - improved hashing in the MMU - faster PageLRU tracking for Intel CPUs without EPT A/D bits - some refactoring of nested VMX entry/exit code, preparing for live migration support of nested hypervisors - expose yet another AVX512 CPUID bit - host-to-guest PTP support - refactoring of interrupt injection, with some optimizations thrown in and some duct tape removed. - remove lazy FPU handling - optimizations of user-mode exits - optimizations of vcpu_is_preempted() for KVM guests * generic: - alternative signaling mechanism that doesn't pound on tsk->sighand->siglock -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQEcBAABAgAGBQJYral1AAoJEL/70l94x66DbNgH/Rx8YXuidFq2fe3RWOvld3RK 85OM/D5g38cTLpBE0/sJpcvX34iYN8U/l5foCZwpxB+83GHEk2Cr57JyfTogdaAJ x8dBhHKQCA/HxSQUQLN6nFqRV+yT8WUR92Fhqx82+80BSen5Yzcfee/TDoW6T1IW g8CYgX9FrRaGOX066ImAuUfdAdUVjyssfs9VttDTX+HiusPeuBPx/wsRe1ZEEPlH vnltIJQb1ETV2GOZLUojKjzH6aZkjIl29XxjkYii9JTUornClG0DfW+5QT3uLrB5 gJ+G+Zmpsq8ZBx9jNDtAi7sFsoPY1Mzf+JPNCGXBra2sP2GrBAuXcxmgznRYltQ= =8IIp -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull KVM updates from Paolo Bonzini: "4.11 is going to be a relatively large release for KVM, with a little over 200 commits and noteworthy changes for most architectures.
