  * Addressing Terminology
  *
- *      NASID - network ID of a router, Mbrick or Cbrick. Nasid values of
- *              routers always have low bit of 1, C/MBricks have low bit
- *              equal to 0. Most addressing macros that target UV hub chips
- *              right shift the NASID by 1 to exclude the always-zero bit.
+ *      M       - The low M bits of a physical address represent the offset
+ *                into the blade local memory. RAM memory on a blade is physically
+ *                contiguous (although various IO spaces may punch holes in
+ *                it)..
  *
- *      SNASID - NASID right shifted by 1 bit.
+ *      N       - Number of bits in the node portion of a socket physical
+ *                address.
+ *
+ *      NASID   - network ID of a router, Mbrick or Cbrick. Nasid values of
+ *                routers always have low bit of 1, C/MBricks have low bit
+ *                equal to 0. Most addressing macros that target UV hub chips
+ *                right shift the NASID by 1 to exclude the always-zero bit.
+ *                NASIDs contain up to 15 bits.
+ *
+ *      GNODE   - NASID right shifted by 1 bit. Most mmrs contain gnodes instead
+ *                of nasids.
+ *
+ *      PNODE   - the low N bits of the GNODE. The PNODE is the most useful variant
+ *                of the nasid for socket usage.
