[ Upstream commit48b5928e18] The current code registers the node as available in the node array before initializing the accessor list. This makes it so that anything which might access the accessor list as a result of allocations will cause an undefined memory access. In one example, an extension to access hmat data during interleave caused this undefined access as a result of a bulk allocation that occurs during node initialization but before the accessor list is initialized. Initialize the accessor list before making the node generally available to the global system.
