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) ?
