It breaks only !COMPAT builds on s390, since only we have the is_compat_task()
function defined for !COMPAT. The reason for that was simply to get rid of a
couple of ugly  #ifdefs.
Note, that we still need to include asm/compat.h in some file since we need the
compat_ptr typedef.
That might be ugly, but I preferred including that header file so we could get
rid of the #ifdefs.
Anyway... the patch below fixes the build issues:
