Compared with the previous IPIV, the IPIV-BUGFIX has the following changes: 1. Use Kconfig to Control whether to enable IPIV. 2. Users use ioctl to control whether to enable IPIV. 3. Use the SMCCC interface for Guest OS to control whether to enable IPIV. 4. make sure vcpu_id == vcpu_idx. 5. the MPIDR cannot be changed When IPIV is enabled. 6. fix bug that ipiv enable is displayed on the host when "kvm-arm.vgic_v4_enable=0 kvm-arm.ipiv_enabled=1" is configured. 7.
