Oh well, I dont use checkpatch but spoke about trailing \

Cant you see them on your screen ?

We had :

#define _this_cpu_generic_to_op(pcp, val, op)				\
do {									\
	unsigned long flags;						\
	local_irq_save(flags);						\
	*__this_cpu_ptr(&(pcp)) op val;					\
	local_irq_restore(flags);					\
} while (0)


You want :

#define _this_cpu_generic_to_op(pcp, val, op)				\
do {									\
	unsigned long flags;						\
	raw_local_irq_save(flags);						\
	*__this_cpu_ptr(&(pcp)) op val;					\
	raw_local_irq_restore(flags);					\
} while (0)


I suggest :

#define _this_cpu_generic_to_op(pcp, val, op)				\
do {									\
	unsigned long flags;						\
	raw_local_irq_save(flags);					\
	*__this_cpu_ptr(&(pcp)) op val;					\
	raw_local_irq_restore(flags);					\
} while (0)


Is it clear now ?
