Looks like this hit next-20140306, when just doing a simple 'make defconfig', I get:

kernel/irq/Kconfig:41:error: recursive dependency detected!
kernel/irq/Kconfig:41: symbol GENERIC_IRQ_CHIP is selected by GPIO_DWAPB
drivers/gpio/Kconfig:131: symbol GPIO_DWAPB depends on IRQ_DOMAIN
kernel/irq/Kconfig:46: symbol IRQ_DOMAIN is selected by GENERIC_IRQ_CHIP

Not sure the best course of action here..
