Pull kvm fixes from Paolo Bonzini: "RISC-V: - Fix compilation without RISCV_ISA_ZICBOM - Fix kvm_riscv_vcpu_timer_pending() for Sstc ARM: - Fix a bug preventing restoring an ITS containing mappings for very large and very sparse device topology - Work around a relocation handling error when compiling the nVHE object with profile optimisation - Fix for stage-2 invalidation holding the VM MMU lock for too long by limiting the walk to the largest block mapping size - Enable stack protection and branch profiling for VHE - Two selftest fixes x86: - add compat implementation for KVM_X86_SET_MSR_FILTER ioctl selftests: - synchronize includes between include/uapi and tools/include/uapi" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: tools: include: sync include/api/linux/kvm.h KVM: x86: Add compat handler for KVM_X86_SET_MSR_FILTER KVM: x86: Copy filter arg outside kvm_vm_ioctl_set_msr_filter() kvm: Add support for arch compat vm ioctls RISC-V: KVM: Fix kvm_riscv_vcpu_timer_pending() for Sstc RISC-V: Fix compilation without RISCV_ISA_ZICBOM KVM: arm64: vgic: Fix exit condition in scan_its_table() KVM: arm64: nvhe: Fix build with profile optimization KVM: selftests: Fix number of pages for memory slot in memslot_modification_stress_test KVM: arm64: selftests: Fix multiple versions of GIC creation KVM: arm64: Enable stack protection and branch profiling for VHE KVM: arm64: Limit stage2_apply_range() batch size to largest block KVM: arm64: Work out supported block level at compile time
