    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
