This functions should accept the type of integer they say to write. Calling
the u32 function with an integer that is actually 32 bit unsigned gives
compiler warnings.

Trivial enough and can be applied independently from the rest of the series.

("does it bring any surprise warnings?")

Your patch has been applied to the master branch.
