Ok, thanks for the information -- that definitely makes it clear that
it cannot go
away anytime soon (though it doesn't stop us from change the
allmodconfig default
if we decide that's a good idea).

Do you know if there are currently any patches against mainline to
make big-endian
work in products, or is everything working out of the box?
