Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM fixes from Radim Krčmář: "ARM: - fix incorrect huge page mappings on systems using the contiguous hint for hugetlbfs - support alternative GICv4 init sequence - correctly implement the ARM SMCC for HVC and SMC handling PPC: - add KVM IOCTL for reporting vulnerability and workaround status s390: - provide userspace interface for branch prediction changes in firmware x86: - use correct macros for bits" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: KVM: s390: wire up bpb feature KVM: PPC: Book3S: Provide information about hardware/firmware CVE workarounds KVM/x86: Fix wrong macro references of X86_CR0_PG_BIT and X86_CR4_PAE_BIT in kvm_valid_sregs() arm64: KVM: Fix SMCCC handling of unimplemented SMC/HVC calls KVM: arm64: Fix GICv4 init when called from vgic_its_create KVM: arm/arm64: Check pagesize when allocating a hugepage at Stage 2
