It is ARM problem as ARM cannot do unaligned acess without causing aligment
trap. It is up to exception code if it decides to fixup, ignore or terminate
offending process. As ignoring might lead to unexpected behaviour and fixups
are time consuming I always choose to kill problematic program (SIGBUS) and
fix the code.

For gcc-4.3.4 and gcc-4.4.3 (based on you patch) which also update
ptxconfigs. It was meant as mere reminder to someone at pengutronix
to wake up and apply :-)
