532 * By conception this is an helper for other part of the driver
533 * like the indirect buffer or semaphore, which both have their
534 * locking.
535 *
536 * Principe is simple, we keep a list of sub allocation in offset
537 * order (first entry has offset == 0, last entry has the highest
538 * offset).
539 *
540 * When allocating new object we first check if there is room at
541 * the end total_size - (last_object_offset + last_object_size) >=
542 * alloc_size. If so we allocate new object there.
543 *
544 * When there is not enough room at the end, we start waiting for
545 * each sub object until we reach object_offset+object_size >=
546 * alloc_size, this object then become the sub object we return.
547 *
548 * Alignment can't be bigger than page size.
549 *
550 * Hole are not considered for allocation to keep things simple.
551 * Assumption is that there won't be hole (all object on same
552 * alignment).
