23 * M - The low M bits of a physical address represent the offset
28 * N - Number of bits in the node portion of a socket physical
31 * NASID - network ID of a router, Mbrick or Cbrick. Nasid values of
34 * right shift the NASID by 1 to exclude the always-zero bit.
37 * GNODE - NASID right shifted by 1 bit. Most mmrs contain gnodes instead
40 * PNODE - the low N bits of the GNODE. The PNODE is the most useful variant

59 * M - number of node offset bits (35 .. 40)
60 * N - number of PNODE bits (0 .. 10)
73 * This value is also the value of the maximum number of non-router NASIDs
93 * frequently referenced and are kept in the per-cpu data areas of each cpu.
