I'm pretty sure this isn't actually dead:

The 'm' option is handled by option parsing, setting the dom0_domid global.

xenbus_master_domid() returns dom0_domid and that is called by both
dom0_init() and, for mini-os, xenbus_map().

So I think this is used by stub-xenstored somehow.

At the least we shouldn't remove the option without also removing all the
above, and that is not 4.6 material at this point IMHO.

Ian.
