Linus, The following changes since commit 42226c989789d8da4af1de0c31070c96726d990c: Linux 5.18-rc7 (2022-05-15 18:08:58 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus for you to fetch changes up to ffd1925a596ce68bed7d81c61cb64bc35f788a9d: KVM: x86: Fix the intel_pt PMI handling wrongly considered from guest (2022-05-25 05:18:27 -0400) ---------------------------------------------------------------- S390: * ultravisor communication device driver * fix TEID on terminating storage key ops RISC-V: * Added Sv57x4 support for G-stage page table * Added range based local HFENCE functions * Added remote HFENCE functions based on VCPU requests * Added ISA extension registers in ONE_REG interface * Updated KVM RISC-V maintainers entry to cover selftests support ARM: * Add support for the ARMv8.6 WFxT extension * Guard pages for the EL2 stacks * Trap and emulate AArch32 ID registers to hide unsupported features * Ability to select and save/restore the set of hypercalls exposed to the guest * Support for PSCI-initiated suspend in collaboration with userspace * GICv3 register-based LPI invalidation support * Move host PMU event merging into the vcpu data structure * GICv3 ITS save/restore fixes * The usual set of small-scale cleanups and fixes x86: * New ioctls to get/set TSC frequency for a whole VM * Allow userspace to opt out of hypercall patching * Only do MSR filtering for MSRs accessed by rdmsr/wrmsr AMD SEV improvements: * Add KVM_EXIT_SHUTDOWN metadata for SEV-ES * V_TSC_AUX support Nested virtualization improvements for AMD: * Support for "nested nested" optimizations (nested vVMLOAD/VMSAVE, nested vGIF) * Allow AVIC to co-exist with a nested guest running * Fixes for LBR virtualizations when a nested guest is running, and nested LBR virtualization support * PAUSE filtering for nested hypervisors Guest support: * Decoupling of vcpu_is_preempted from PV spinlocks ---------------------------------------------------------------- As Catalin mentioned, there is a small conflict in arch/arm64/kvm/sys_regs.c; the linux.git version is already the correct resolution of the conflict.
