cris: fix integer overflow in ELF_ET_DYN_BASE
Almost all arches define ELF_ET_DYN_BASE as 2/3 of TASK_SIZE. Though it seems that some architectures do this in a wrong way. The problem is that 2*TASK_SIZE may overflow 32-bits so the real ELF_ET_DYN_BASE becomes wrong. Fix this overflow by dividing TASK_SIZE prior to multiplying: (TASK_SIZE / 3 * 2) Signed-off-by: Andrey Ryabinin <a.ryabinin@samsung.com> Signed-off-by: Jesper Nilsson <jespern@axis.com>
