This adds support for a generic reservations framework that can be hooked up to ttm and dma-buf and allows easy sharing of reservations across devices. The idea is that a dma-buf and ttm object both will get a pointer to a struct reservation_object, which has to be reserved before anything is done with the contents of the dma-buf. Changes since v1: - Fix locking issue in ticket_reserve, which could cause mutex_unlock to be called too many times. Changes since v2: - All fence related calls and members have been taken out for now, what's left is the bare minimum to be useful for ttm locking conversion. Changes since v3: - Removed helper functions too. The documentation has an example implementation for locking. With the move to ww_mutex there is no need to have much logic any more.
