s390: Do not rely on magic indirect includes
commit: 8f945a33 (genirq: Move kstat_incr_irqs_this_cpu() to core)
unearthed the following:
arch/s390/kernel/irq.c: In function 'init_IRQ':
>> arch/s390/kernel/irq.c:93:2: error: implicit declaration of function 'irq_reserve_irqs'
[-Werror=implicit-function-declaration]
....
cc1: some warnings being treated as errors
--
drivers/s390/cio/cio.c: In function 'init_cio_interrupts':
>> drivers/s390/cio/cio.c:594:2: error: implicit declaration of function
'irq_set_chip_and_handler' [-Werror=implicit-function-declaration]
[-Werror=implicit-function-declaration]
....
cc1: some warnings being treated as errors
The reason is that those files require linux/irq.h and magically
pulled that in via linux/kernel_stat.h
The commit above got rid of the pointless include of linux/irq.h in
linux/kernel_stat.h and therefor broke the build.
Include linux/irq.h
