The initial motivation for giving hmat.c its own directory was to delineate it as mm functionality in contrast to ACPI device driver functionality. As ACPI continues to play an increasing role in conveying memory location and performance topology information to the OS take the opportunity to co-locate these NUMA relevant tables in a combined directory. numa.c is renamed to srat.c and moved to drivers/acpi/numa/ along with hmat.c.
