Thanks, you're right. You have to admit, it's pretty amusing how many
times roundup_pow_of_two() expands its argument (via ilog2)...
Anyway, I have this queued up to fix it. I'll ask Linus to pull shortly.

IB/mlx4: Fix warning in rounding up queue sizes
Doing max(1, foo) where foo is u32 generates a warning, because 1 is a
signed constant. Fix this by using 1U instead.
