Hello all, I would like you to comment the following patch. At the some moment, I was faced to problem with syscall sys_shmat in 32-bit mode on 64-bit platforms. I have fixed the function in the same manner as native sys_shmat had been: sys_shmat expects pointer to memory as the return value rather than put_user'ed to the memory pointed by 3rd parameter.
