After some more thoughts it's obvious that we should do the
return-PC-tweaking according to the "custom ie" flag in the ISR entry
code rather than in the Kernel exit code, as the exit will go to another
process than the one that was interrupted ans did set the flag. I don't
know if that is more difficult than using the exit code (as blackfin does).
