lock order reversal with 5.2-CURRENT as of 12/11

[Michael L. Squires]

This is a new one for me:

kernel: lock order reversal
kernel: 1st 0xc0993b00 UMA lock (UMA lock) @ /usr/src/sys/vm/uma_core.c:1200
kernel: 2nd 0xc1031100 system map (system map) @ /usr/src/sys/vm/vm_map.c:2210
kernel: Stack backtrace:
<rest not logged>

System is SM P6DGH, dual PIII/850, 1GB RAM, SCSI disks, SMP kernel with
a number of options including NETATALK and some SYSV things for postgreSQL.

FreeBSD 5.2-CURRENT of Thu Dec 11 18:52:09 (cvsup'd about an hour before
compilation).  Complete buildworld/installworld and portupgrade also run.

If this is of any interest I can provide more data.
