I asume that you have a meaningful commit message and that reviewboard screwed up.  I don't want to be too anal here so feel free to overrule me, but is ltz a standard name in ARM?  If not, perhaps we should try to standardize these names somehow.  In Python, comparisons are named lt, gt, geq, leq, eq, and neq.  It's not a big deal, but I didn't immediately know what ltz meant without looking at the code.  Anyway I leave it up to you.
