hw/intc/arm_gicv3_redist: Implement gicv3_redist_vinvall()
Implement the gicv3_redist_vinvall() function (previously left as a stub). This function handles the work of a VINVALL command: it must invalidate any cached information associated with a specific vCPU. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-id: 20220408141550.1271295-36-peter.maydell@linaro.org
