ARM: CORTEX M, PRIMASK does not disable interrupts

qemu version 0.15.1
but the same code is in qemu 1.0

"CPSID I" does not disable interrupts for CORTEX M3


if (interrupt_request & CPU_INTERRUPT_HARD
                        && ((IS_M(env) && env->regs[15] < 0xfffffff0)
                            || !(env->uncached_cpsr & CPSR_I))) {
                        env->exception_index = EXCP_IRQ;
                        do_interrupt(env);
                        next_tb = 0;
                    }


do_interrupt() will be executed even if (env->uncached_cpsr & CPSR_I) == 1 , disable interrupt bit set.


then changed to: 

if (interrupt_request & CPU_INTERRUPT_HARD 
                        && !(env->uncached_cpsr & CPSR_I)
                        && (IS_M(env) ? env->regs[15] < 0xfffffff0: 1) ) {
                        env->exception_index = EXCP_IRQ;
                        do_interrupt(env);
                        next_tb = 0;
                    }

works
