OK. I guess you are planning to submit the LTP patch at some point (once
kernel and glibc changes are agreed).

Any plans for big-endian ILP32?

I forgot to mention dropping the full stop at the end of every subject.

More coding style issues: please have a look at
Documentation/CodingStyle. While I'm not usually bothered with minor
aspects, I would like at least some consistency for multi-line comment
style.

Also please get the patches through checkpatch.pl (it doesn't need to be
100% pass but it gives some clues).

There are a few #defines you added without corresponding brackets (hpa
commented on one already).
