I like the idea - anything we can remove from the writeback path is
useful in terms of stack footprint. I've had a quick look over the
patches and can't see any obvious issues, but I need to do a more
in-depth review of them over the next couple of days. In the mean
time, I'll add them to my QA stack...

Cheers,

Dave.
