This commit has been processed because it contains a "Fixes:" tag, fixing commit: 98f4a1467612 KVM: add kvm_arch_vcpu_runnable() test to kvm_vcpu_on_spin() loop.

The bot has tested the following trees: v5.2.4, v5.1.21, v4.19.62, v4.14.134, v4.9.186, v4.4.186.

v5.2.4: Build failed! Errors: arch/arm64/kvm/../../../virt/kvm/kvm_main.c:2483:31: error: ‘struct kvm_vcpu’ has no member named ‘async_pf’

v5.1.21: Build failed! Errors: arch/arm64/kvm/../../../virt/kvm/kvm_main.c:2415:31: error: ‘struct kvm_vcpu’ has no member named ‘async_pf’

Thanks for reporting this, after more grep, it seems that just x86 and s390 enable async_pf in their Makefile. So I can move 'if (!list_empty_careful(&vcpu->async_pf.done))' checking to kvm_arch_dy_runnable(), Paolo, do you have more comments to v3 before I send a new version?
