Subject: [PATCH] mm/memprofiling: explicitly include irqflags.h in alloc_tag.h
Date: Sun,  7 Apr 2024 15:32:52 +0200

linux/alloc_tag.h uses the macro this_cpu_inc which eventually expands to:

 #define this_cpu_generic_to_op(pcp, val, op)				\
 do {									\
 	unsigned long __flags;						\
 	raw_local_irq_save(__flags);					\
 	raw_cpu_generic_to_op(pcp, val, op);				\
 	raw_local_irq_restore(__flags);					\
 } while (0)

The macros raw_local_irq_save and raw_local_irq_restore are defined in
linux/irqflags.h which is not included implicitly on all configs.
Therefore, include it explicitly.
