Previously, futex code of McKerenl was called by mccontrol, but there ware some problems with this method. (Mainly, location of McKernel image on memory) Call futex code in mcctrl instead of the one in McKernel image, giving the following benefits: 1. Not relying on shared kernel virtual address space with Linux any more 2. The cpu id store / retrieve is not needed and resulting in the code Change-Id: Ic40929b64a655b270c435859fa287fedb713ee5c refe: #1428
