commit d7e51e66899f95dabc89b4d4c6674a6e50fa37fc
Author: Yinghai Lu <yinghai@kernel.org>

sparseirq: make some func to be used with genirq

breaks the sparc64 build:

arch/sparc/kernel/irq_64.c: In function ‘show_interrupts’:
arch/sparc/kernel/irq_64.c:188: error: ‘struct kernel_stat’ has no member named ‘irqs’
make[1]: *** [arch/sparc/kernel/irq_64.o] Error 1

This should fix it:

sparc64: Fix build by using kstat_irqs_cpu().

Changeset d7e51e66899f95dabc89b4d4c6674a6e50fa37fc ("sparseirq: make
some func to be used with genirq") broke the build on sparc64:

arch/sparc/kernel/irq_64.c: In function ‘show_interrupts’:
arch/sparc/kernel/irq_64.c:188: error: ‘struct kernel_stat’ has no member named ‘irqs’
make[1]: *** [arch/sparc/kernel/irq_64.o] Error 1

Fix by using the kstat_irqs_cpu() interface.
