Sorry for the confusion: my brain is on a one-week vacation, and I'm
blathering. I told you to change a line in mm/swapfile.c from

if (!mm)
return 0;

to

if (!mm && mm != &init_mm)
return 0;

but it should _obviously_ be

if (!mm || mm == &init_mm)
return 0;

Duh. Silly me. (The test just makes sure we don't try to unmap any kernel
pages)
