Matthew Wilcox 08d9a4580f tee: shm: Remove refcounting of kernel pages ... Earlier TEE subsystem assumed to refcount all the memory pages to be shared with TEE implementation to be refcounted. However, the slab allocations within the kernel don't allow refcounting kernel pages. It is rather better to trust the kernel clients to not free pages while being shared with TEE implementation. Hence, remove refcounting of kernel pages from register_shm_helper() API.
