Step to reproduce:

  1. Apply PR add android cmake support over the BVLC/caffe opencl (issue #48) #50 and PR OpenCl kernel compilation errors for android #51 based on opencl branch to get android version of caffe binary with required libs

  2. run caffe time comand and got error

and strange artifacts on the screen while processing caffe command atleast for Galaxy Note 4 with Mali GPU:

I0202 16:24:37.476721  5890 common.cpp:405] Device id:                     0
I0202 16:24:37.476784  5890 common.cpp:407] Device backend:                OpenCL
I0202 16:24:37.476850  5890 common.cpp:409] Backend details:               ARM: OpenCL 1.1 
I0202 16:24:37.476951  5890 common.cpp:411] Device vendor:                 ARM
I0202 16:24:37.477020  5890 common.cpp:413] Name:                          Mali-T760
I0202 16:24:37.477088  5890 common.cpp:415] Total global memory:           2147483648

So as solution provide compilation param
DISABLE_DEVICE_HOST_UNIFIED_MEMORY
to force disabling support host unified memory
