Is there ANY Cortex core that supports reentrant interrupts?

For some (external to me) reason I am stuck with the Cortex but trying to find work around to my software issues with the lack of reentrant interrupts in CM3. Does CM4 support reentrancy? Or maybe CM0? Anything at all?
Please help!

    Thanks Marcus. Yes I was referring to M3 and if you are right that actually gives me hope as I was comfortably using the ARM7's VIC with re-entrant interrupts. There was even an application note (from NXP, I think) that described that. So I am trying to find something similar for this poor new chip as well.
