2016-09-09arm64/numa: avoid inconsistent information to be printedZhen Lei
numa_init may return error because of numa configuration error. So "No NUMA configuration found" is inaccurate. In fact, specific configuration error information should be immediately printed by the testing branch.

2016-05-30arm64, ACPI, NUMA: NUMA support based on SRAT and SLITHanjun Guo
Introduce a new file to hold ACPI based NUMA information parsing from SRAT and SLIT. SRAT includes the CPU ACPI ID to Proximity Domain mappings and memory ranges to Proximity Domain mapping. SLIT has the information of inter node distances(relative number for access latency).
