Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

- * used to avoid destruction while the buffer object is still on a list.

- * @event_queue: Queue for processes waiting on buffer object status change.
- * @mem: structure describing current placement.
- * @persistent_swap_storage: Usually the swap storage is deleted for buffers
- * pinned in physical memory. If this behaviour is not desired, this member
- * holds a pointer to a persistent shmem object.
- * @ttm: TTM structure holding system pages.
- * @evicted: Whether the object was evicted without user-space knowing.
- * @cpu_writes: For synchronization. Number of cpu writers.
- * @lru: List head for the lru list.
- * @ddestroy: List head for the delayed destroy list.
- * @swap: List head for swap LRU list.
- * @val_seq: Sequence of the validation holding the @reserved lock.
- * Used to avoid starvation when many processes compete to validate the
- * buffer. This member is protected by the bo_device::lru_lock.
- * @seq_valid: The value of @val_seq is valid. This value is protected by
- * the bo_device::lru_lock.
- * @reserved: Deadlock-free lock used for synchronization state transitions.
- * @sync_obj_arg: Opaque argument to synchronization object function.
- * @sync_obj: Pointer to a synchronization object.
- * @priv_flags: Flags describing buffer object internal state.
- * @vm_rb: Rb node for the vm rb tree.
- * @vm_node: Address space manager node.
- * @offset: The current GPU offset, which can have different meanings
- * depending on the memory type. For SYSTEM type memory, it should be 0.
- * @cur_placement: Hint of current placement.
- *
- * Base class for TTM buffer object, that deals with data placement and CPU
- * mappings. GPU mappings are really up to the driver, but for simpler GPUs
- * the driver can usually use the placement offset @offset directly as the
- * GPU virtual address. For drivers implementing multiple
- * GPU memory manager contexts, the driver should manage the address space
- * in these contexts separately and use these objects to get the correct
- * placement and caching for these GPU maps. This makes it possible to use
- * these objects for even quite elaborate memory management schemes.
- * The destroy member, the API visibility of this object makes it possible
- * to derive driver specific types.

- * Locks a buffer object for validation. (Or prevents other processes from

- *
- * Deadlocks may occur when two processes try to reserve multiple buffers in
- * different order, either by will or as a result of a buffer being evicted
- * to make room for a buffer already reserved. (Buffers are reserved before
- * they are evicted). The following algorithm prevents such deadlocks from
- * occurring:
- * 1) Buffers are reserved with the lru spinlock held. Upon successful
- * reservation they are removed from the lru list. This stops a reserved buffer
- * from being evicted. However the lru spinlock is released between the time
- * a buffer is selected for eviction and the time it is reserved.
- * Therefore a check is made when a buffer is reserved for eviction, that it
- * is still the first buffer in the lru list, before it is removed from the
- * list. @check_lru == 1 forces this check. If it fails, the function returns
- * -EINVAL, and the caller should then choose a new buffer to evict and repeat
- * the procedure.
- * 2) Processes attempting to reserve multiple buffers other than for eviction,
- * (typically execbuf), should first obtain a unique 32-bit
- * validation sequence number,
- * and call this function with @use_sequence == 1 and @sequence == the unique
- * sequence number. If upon call of this function, the buffer object is already
- * reserved, the validation sequence is checked against the validation
- * sequence of the process currently reserving the buffer,
- * and if the current validation sequence is greater than that of the process
- * holding the reservation, the function returns -EAGAIN. Otherwise it sleeps
- * waiting for the buffer to become unreserved, after which it retries
- * reserving.
- * The caller should, when receiving an -EAGAIN error
- * release all its buffer reservations, wait for @bo to become unreserved, and
- * then rerun the validation with the same validation sequence. This procedure
- * will always guarantee that the process with the lowest validation sequence
- * will eventually succeed, preventing both deadlocks and starvation.
- *
- * Returns:
- * -EAGAIN: The reservation may cause a deadlock.
- * Release all buffer reservations, wait for @bo to become unreserved and
- * try again. (only if use_sequence == 1).
- * -ERESTARTSYS: A wait for the buffer to become unreserved was interrupted by
- * a signal. Release all buffer reservations and return to user-space.
