The check in do_alignment_ldmstm for addr and eaddr being the same is #ifdef'd
out for the ARM922T because they aren't expected to be the same due to the 
different way the MMU sets addr. The ARM920T is just a 922T with more cache, 
and should be treated the same. I've checked on a real ARM920T and it does 
complain loudly every time it fixes up a misaligned ldm/stm unless this 
patch is applied.
 I suspect that the ARM926 should be treated the same way as well, but I can't
find any relevant documentation on ARM's web-site, so have left it out.
