Getting rid of alignment faults in userspace

Hi all, I've recently become aware that a few packages are causing alignment faults on ARM, and are relying on the alignment fixup emulation code in the kernel in order to work. Such faults are very expensive in terms of CPU cycles, and can generally only result from wrong code (for example, C/C+
