What I'm concerned about is the apparant lack of exposure of the patch
to people outside of ARM, especially as it touches lib/xz/xz_dec_stream.c.

I have no idea whether that breaks some architecture or not.

Is Lasse Collin (the original contributer of that file) aware of this
change?

What is the additional include fixing on ARM?  Why isn't this include
needed on other architectures?  And why isn't any of this mentioned in
the patch commit log?
