3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 42acfc6615f47e465731c263bee0c799edb098f2 upstream. In csi_J(3), the third parameter of scr_memsetw (vc_screenbuf_size) is divided by 2 inappropriatelly. But scr_memsetw expects size, not count, because it divides the size by 2 on its own before doing actual memset-by-words. So remove the bogus division.
