This is a bit of a kludge, but you may try something similar to Juanjo's
patch, but check explicitly for kzalloc in the header file:

kzalloc := $(shell grep "kzalloc" $(TOPDIR)/include/linux/slab.h 2> /dev/null)
ifneq ($(strip $(kzalloc)),)
CFLAGS += -DHAVE_KZALLOC
endif

Of course, the code would have:

#ifndef HAVE_KZALLOC
void * kzalloc(size_t size, unsigned flgs)
...

I haven't tested this.  :-)
