If the kexec crash code is called in the interrupt context, the machine_kexec_mask_interrupts() function will trigger a deadlock while trying to acquire the irqdesc spinlock and then deacitive irqchip. To avoid the deadlock, this patch directly EOI the irq regardless of the active status of irqchip.
