For quite a while now spu state is protected by a simple mutex instead of the old rw_semaphore, and this means we can simplify the locking around spu_setup_isolated a lot. Instead of doing an spu_release before entering spu_setup_isolated and then calling the complicated spu_acquire_exclusive we can now simply enter the function locked an in guaranteed runnable state, so that the only bit of spu_acquire_exclusive that's left is the call to spu_unmap_mappings. Similarly there's no more need to unlock and reacquire the state_mutex when spu_setup_isolated is done, but we can always return with the lock held and only drop it in spu_run_init in the failure case.
