 When there are multiple interrupts performing the same function, for example 2 UARTs which are trying to wake up the device, it is not necessary that you connect two interrupts. You can just gang the pins together and provide a common isr to the ganged pins. 

In the isr if you can check out which pin caused the interrupt and find out the corresponding UART wake up source.

If you have unused pins then this can serve as better .
