Mark Johnston 991f23ef20 uma: Avoid allocating buckets with the cross-domain lock held ... Allocation of a bucket can trigger a cross-domain free in the bucket zone, e.g., if the per-CPU alloc bucket is empty, we free it and get migrated to a remote domain. This can lead to deadlocks since a bucket zone may allocate buckets from itself or a pair of bucket zones could be allocating from each other. Fix the problem by dropping the cross-domain lock before allocating a new bucket and handling refill races. Use a list of empty buckets to ensure that we can make forward progress.
