I have a fix I'm testing for this but it's going to need a lot of
randconfig build testing on all archs.
Philip, could 0day help out with that? I don't know how you schedule
which branches for which testing, and previously the memory allocation
profiling didn't get enough build testing before Andrew merged it.
Running my own build testing now, of course...

Got it, we will cover this branch with randconfig build tests.

Sorry about this, we really need extend the test number to generate
more randconfigs.

It was getting caught by 0day in Andrew's tree, I think it may have just
been a timing thing. This is (one of the reasons) why I'm hoping to get
you a dashboard (and maybe get some test infrastructure consolidation
going, too) - right now I just have no way of knowing how long the
randconfig tests take or when they're finished.
