- New page table code for both hypervisor and guest stage-2 - Introduction of a new EL2-private host context - Allow EL2 to have its own private per-CPU variables - Support of PMU event filtering - Complete rework of the Spectre mitigation PPC: - Fix for running nested guests with in-kernel IRQ chip - Fix race condition causing occasional host hard lockup - Minor cleanups and bugfixes x86: - allow trapping unknown MSRs to userspace - allow userspace to force #GP on specific MSRs - INVPCID support on AMD - nested AMD cleanup, on demand allocation of nested SVM state - hide PV MSRs and hypercalls for features not enabled in CPUID - new test for MSR_IA32_TSC writes from host and guest - cleanups: MMU, CPUID, shared MSRs - LAPIC latency optimizations ad bugfixes For x86, also included in this pull request is a new alternative and (in the future) more scalable implementation of extended page tables that does not need a reverse map from guest physical addresses to host physical addresses. For now it is disabled by default because it is still lacking a few of the existing MMU's bells and whistles. However it is a very solid piece of work and it is already available for people to hammer on it. -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAl+S8dsUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroM40Af+M46NJmuS5rcwFfybvK/c42KT6svX Co1NrZDwzSQ2mMy3WQzH9qeLvb+nbY4sT3n5BPNPNsT+aIDPOTDt//qJ2/Ip9UUs tRNea0MAR96JWLE7MSeeRxnTaQIrw/AAZC0RXFzZvxcgytXwdqBExugw4im+b+dn Dcz8QxX1EkwT+4lTm5HC0hKZAuo4apnK1QkqCq4SdD2QVJ1YE6+z7pgj4wX7xitr STKD6q/Yt/0ndwqS0GSGbyg0jy6mE620SN6isFRkJYwqfwLJci6KnqvEK67EcNMu qeE017K+d93yIVC46/6TfVHzLR/D1FpQ8LZ16Yl6S13OuGIfAWBkQZtPRg== =AD6a -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull KVM updates from Paolo Bonzini: "For x86, there is a new alternative and (in the future) more scalable implementation of extended page tables that does not need a reverse map from guest physical addresses to host physical addresses.
