v4: https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1493704.html
Right, this is hopefully the last version - I've put things back in a sensible order with the new additions at the end, so if they prove contentious the first 4 previously-tested patches can still get their time in -next. Patch #3 is updated to fix the bug brought to light by Tomasz, patch #6 includes the cleanup afterthought from v4, and I've nobbled one or two rogue whitespace changes I'd missed before. And the diffstat is still even more negative than before, hooray! For the whole series, the total code size reduction of alloc_iova() comes to just over 26% (AArch64 GCC 6.3.1). Robin.
