// DiaKGCN 24-02-2012 - OpenCL kernel by Diapolo
// DiaKGCN 16-03-2012 - OpenCL kernel by Diapolo
//
// Parts and / or ideas for this kernel are based upon the public-domain poclbm project, the phatk kernel by Phateus and the DiabloMiner kernel by DiabloD3.
// The kernel was rewritten by me (Diapolo) and is still public-domain!
