Hi,

I've just enabled alignment faults for arm32. This will catch all 
misaligned loads/stores, which previously silently failed, leading to 
possible data corruption.

In order to support older a.out binaries (in which gcc made use of 
misaligned accesses for short ints under certain circumstances), the 
kernel will dynamically disable alignment faults just before executing 
a.out userland code, and re-enable them on entry back into the kernel. 
This feature is automatically enabled when both COMPAT_15 and EXEC_AOUT 
are defined.

Enjoy.

Cheers, Steve
