If anyone has any objections, please let me know. ------------------ From: Huacai Chen commit a9c3ee5d0fdb069b54902300df6ac822027f3b0a upstream. The liointc hardware provides separate Interrupt Status Registers (ISR) for each core. The current code uses always the ISR of core #0, which works during boot because by default all interrupts are routed to core #0. When the interrupt routing changes in the firmware configuration then this causes interrupts to be lost because they are not configured in the corresponding core. Use the core index to access the correct ISR instead of a hardcoded 0.
