* @lock: spinlock protecting mostly synchronization members.
* @mem: structure describing current placement.
* @persistant_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 persistant shmem object.
* @ttm: TTM structure holding system pages.
* @evicted: Whether the object was evicted without user-space knowing.

* @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.

* 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
* locking it for validation) and removes it from lru lists, while taking
* a number of measures to prevent deadlocks.
*
* 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
* occuring:
* 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).
