While the patch appears to be trivial, I had to grab the above mentioned ARM
manual
and read a bit from there. Unfortunately, since I don't have any prior knowlege
about this stuff, at all, I still have to accept for granted that it is the
right
thing to do. Maybe it is better to route this to the ARM maintainer instead
(Cc'ed) ?
