Just checked 3.10.17 and there the size of gcsHAL_INTERFACE is 248, the 
same as used by the libs in gpu-viv-bin-mx6q-3.10.31-1.1.0-beta. So the 
libs seem to have been compiled against headers with an old 
gcsHAL_INTERFACE and are therefor unusable with kernel 3.10.31.

Here is a small test program one can check against kernel 3.10.17 and 
3.10.31:

-----------------------------
#include <stdio.h>

#include "/usr/src/linux/drivers/mxc/gpu-viv/hal/kernel/inc/gc_hal.h"

int main(void)
{
         printf("Size: %u\n", sizeof(gcsHAL_INTERFACE));
         return 0;
}
-----------------------------
