Blackfin arch: fix bug - jump_to_zero test case failed on noMPU kernel
The nompu code is now derived from the mpu code, and had the same problem - no null pointer detection on ICPLBs. Signed-off-by: Bernd Schmidt <bernds_cb1@t-online.de> Cc: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>
