With all the previous patches there shouldn't be anything lying on the reservations being atomic with removal of the bo's from the lru lists any more.
As such we can finally fix the locking primitives and make it act like normal mutex calls.
Patch 1 is the actual removal of the guarantee in ttm_bo_reserve patch 2 is a cleanup of ttm_eu_backoff_reservation from removing that guarantee patch 3...6 are introducing ttm_bo_reserve_slowpath.
After this series, this should directly map to my proposed extensions to mutex.

Few comments in some patches but nothing important.
Actually while about to send my comments i thought of some bad scenario see patch 4.
