Are you writing kernel module ? or you try to compile kernel with cmem module ? What hardware are you using ? How are you allocating shmem ? Can you give few code lines for what you try ? The more info you give, more help you receive. Well, it may be faster to go directly to some kernel list or vendor list with your questions.
