static inline bool arch_irqs_disabled_flags(unsigned long flags)
In powerpc/64, the arch_local_irq_disable() function returns unsigned long, which is not consistent with other architectures. Move that set-return asm implementation into arch_local_irq_save(), and make arch_local_irq_disable() return void, simplifying the assembly.
