local_irq_save() should be a macro, not a function
because local_irq_save() saves flag to the given argument.

GCC is silent about this issue, but Clang warns:

In file included from lib/asm-offsets.c:15:
In file included from include/common.h:20:
In file included from include/linux/bitops.h:110:

      [-Wuninitialized]
        local_irq_save(flags);
                       ^~~~~

That change causes another warning:

So, flags should be set to __always_unused.
