Applied fix mentioned in bugreport 3370. Seems to solve the issue.
fixed comparison to stop integer wrap around
fixed compilation with CUDA 6.0:

GpuMat::setTo function, removed NPP call for CV_8S
Fixed little issue with mouse callback refering to issue 3409. Was using round instead of floor.
facedetect
multithreading facedetector
ocl: added workaround into Haar kernels
ocl::BruteForceMatcher fix wrong use of oclMat::ptr().

The oclMat::ptr() method was mistakenly used in ocl::BruteForceMatcher to pass a pointer to a oclMat object. The ptr() method returns a uchar pointer to the cl_mem data structure and this method will be removed.

Removing ocl::oclMat::ptr() method.

The method ocl::oclMat::ptr() is being removed because it returns a pointer to a row of oclMat::data. The data attribute is a cl_mem structure and cannot be iterated outside an OpenCL kernel.
