   Could you elaborate on the reasoning here? Adding -ffreestanding broke
   everything that used alloca(), which seems to include a chunk of
   cardbus, macppc kernels, and the generic ofw_subr code.


either alloca shouldn't be used or the builtin should be used ...
(i'm guessing the latter, see libkern.h i think).


jason, shouldn't bsd.lkm.mk also have it?
