Hi Jason,

After merging the irqchip tree, today's linux-next build (x86_64
allmodconfig) failed like this:

kernel/irq/generic-chip.c: In function 'irq_map_generic_chip':
kernel/irq/generic-chip.c:408:2: error: implicit declaration of function 'irq_domain_set_info' [-Werror=implicit-function-declaration]
  irq_domain_set_info(d, virq, hw_irq, chip, gc, ct->handler, NULL, NULL);
  ^

Caused by commit 3f6b2c298240 ("genirq: Generic chip: Support hierarchy
domain").  The only declaration of irq_domain_set_info() depends on
CONFIG_IRQ_DOMAIN_HIERARCHY.

I have used the irqchip tree from next-20150410 fot today.
