Linus Torvalds 10dc374766 One of the largest releases for KVM... Hardly any generic improvement, ... but lots of architecture-specific changes. * ARM: - VHE support so that we can run the kernel at EL2 on ARMv8.1 systems - PMU support for guests - 32bit world switch rewritten in C - various optimizations to the vgic save/restore code. * PPC: - enabled KVM-VFIO integration ("VFIO device") - optimizations to speed up IPIs between vcpus - in-kernel handling of IOMMU hypercalls - support for dynamic DMA windows (DDW). * s390: - provide the floating point registers via sync regs; - separated instruction vs. data accesses - dirty log improvements for huge guests - bugfixes and documentation improvements. * x86: - Hyper-V VMBus hypercall userspace exit - alternative implementation of lowest-priority interrupts using vector hashing (for better VT-d posted interrupt support) - fixed guest debugging with nested virtualizations - improved interrupt tracking in the in-kernel IOAPIC - generic infrastructure for tracking writes to guest memory---currently its only use is to speedup the legacy shadow paging (pre-EPT) case, but in the future it will be used for virtual GPUs as well - much cleanup (LAPIC, kvmclock, MMU, PIT), including ubsan fixes. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQEcBAABAgAGBQJW5r3BAAoJEL/70l94x66D2pMH/jTSWWwdTUJMctrDjPVzKzG0 yOzHW5vSLFoFlwEOY2VpslnXzn5TUVmCAfrdmFNmQcSw6hGb3K/xA/ZX/KLwWhyb oZpr123ycahga+3q/ht/dFUBCCyWeIVMdsLSFwpobEBzPL0pMgc9joLgdUC6UpWX tmN0LoCAeS7spC4TTiTTpw3gZ/L+aB0B6CXhOMjldb9q/2CsgaGyoVvKA199nk9o Ngu7ImDt7l/x1VJX4/6E/17VHuwqAdUrrnbqerB/2oJ5ixsZsHMGzxQ3sHCmvyJx WG5L00ubB1oAJAs9fBg58Y/MdiWX99XqFhdEfxq4foZEiQuCyxygVvq3JwZTxII= =OUZZ -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull KVM updates from Paolo Bonzini: "One of the largest releases for KVM...
