Makes perfect sense.

I'm going to split the patch into an actual "Fixes:" and a refactoring
part, reword the fix portion to make the reference clearer that any
32bit arch is affected, take a closer look at the call tree to where
else clone_flags is passed to and explicitly Cc: the stable list for the
bugfix commit in series v2.

Best regards
Simon
