Hi,

I saw a recent commit in armv7 which fixed some KNF but added some
trailing white spaces.
I already saw some commit that removed trailing white spaces and thought
about sending a patch (actually joined here).
I usually don't send this kind of patch as it's not usually accepted:
- it doesn't do anything useful except saving a few bytes
- it modifies code history so it makes it harder to track functional
  changes

I, myself, clean the useless white spaces in my code.

So here is a patch against sys/arch/armv7 that remove trailing
white spaces. When cleaning, I found an extraneous ";".

If you think it's useful, I'll submit more, by subsystems.

Here is the part of the patch which doesn't remove only spaces
(git diff -b):
