Just a quick note that I've got some kernel processes with negative RSS
on my latest (3 day old) 1.4BETA kernel:

USER       PID %CPU %MEM   VSZ  RSS TT  STAT STARTED       TIME COMMAND
root         0  0.0 -119.5     0 -117480 ??  DLs  10:31AM    0:00.03 (swapper)
root         2  0.0 -119.5     0 -117480 ??  DL   10:31AM    0:00.01 (pagedaemon)
root         3  0.0 -119.5     0 -117480 ??  DL   10:31AM    0:05.04 (reaper)

I thought Michael's pmap changes in mips/mips/pmap.c rev 1.52 (from
early March) had fixed this.  Is anyone seeing this problem?

Simon.
