Make hard_irq_disable() actually hard-disable interrupts
At present, hard_irq_disable() does nothing on powerpc because of this code in include/linux/interrupt.h: #ifndef hard_irq_disable #define hard_irq_disable() do { } while(0) #endif So we need to make our hard_irq_disable be a macro. It was previously a macro until commit 7230c56441 ("powerpc: Rework lazy-interrupt handling") changed it to a static inline function.
