Please don't top post.

Ok, so if we really want to change the code to be able to handle 
!TARGET_WORDS_BIGENDIAN the whole notion of s->le_mode becomes flawed. 
Instead, it should get renamed into needs_swab or needs_byteswap or 
something along those lines. Then we can set it accordingly based on 
msr_le and target configuration.

For the mem_helper.c changes, could you please explain why you have to 
treat msr_le and needs_byteswap separately?


Thanks,
