mstartfn is used to start a few special purpose functions on a new M. Specifically, in current master, the possible values are sysmon (the system monitor thread), mhelpgc (a new thread ready to help the GC in the future), and mspinning (starts the new thread in spinning state to maintain some bookkeeping).
