arch/arm64/kvm/mmu.c:1203:9-10: WARNING: return of 0/1 in function 'kvm_age_gfn' with return type bool
arch/arm64/kvm/mmu.c:1173:9-10: WARNING: return of 0/1 in function 'kvm_set_spte_gfn' with return type bool
arch/arm64/kvm/mmu.c:1216:9-10: WARNING: return of 0/1 in function 'kvm_test_age_gfn' with return type bool
arch/arm64/kvm/mmu.c:1159:9-10: WARNING: return of 0/1 in function 'kvm_unmap_gfn_range' with return type bool
