[POWERPC] cell: Add routines for managing PMU interrupts
The following routines are added to arch/powerpc/platforms/cell/pmu.c: cbe_clear_pm_interrupts() cbe_enable_pm_interrupts() cbe_disable_pm_interrupts() cbe_query_pm_interrupts() cbe_pm_irq() cbe_init_pm_irq() This also adds a routine in arch/powerpc/platforms/cell/interrupt.c and some macros in cbe_regs.h to manipulate the IIC_IR register: iic_set_interrupt_routing() Signed-off-by: Kevin Corry <kevcorry@us.ibm.com> Signed-off-by: Carl Love <carll@us.ibm.com> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
