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...
