1) You export this function here

2) You change that in one of the next patches to something else

3) According to patch 1/8 X86_FEATURE_SPLIT_LOCK_DETECT is not set when
   sld_state == sld_off. FYI, I did that on purpose.

AFAICT #1 and #2 are just historical leftovers of your previous patch
series and the extra step was just adding more changed lines per patch
for no value.

#3 changed the detection mechanism and at the same time the semantics of
the feature flag.

So what's the point of this exercise? 

Thanks,
